PolarPro VND Filter Peter McKinnon Edition II: Two-minute review

The latest product of PolarPro’s ongoing collaboration with hugely popular videographer and YouTube creator Peter McKinnon, the VND Filter Peter McKinnon Edition II has become an interesting and valuable part of my camera setup over the past few weeks.

First, a quick explanation of what a ND filter does. One of the key principles of photography and videography is the so-called “exposure triangle” – the way that ISO, aperture and shutter speed interact to control the amount of light that hits an image sensor.

By adding a neutral-density (ND) filter – which reduces the amount of light coming in without affecting the color hue – to the equation, photographers gain one extra factor to influence how the camera behaves, and more control over shutter speed and aperture.

For photographers, the ability to reduce light means we can use longer shutter speeds than the lighting conditions would ordinarily allow. That means artfully blurred waterfalls, or night-time shots with streaking, laser-like car headlights. For videographers, control over shutter speed allows for motion blur and wide-open aperture shooting in brighter conditions.

The main selling point of the PolarPro VND Filter Peter McKinnon Edition II (also known as the PMVND II) is that it’s a variable ND filter. In other words, twisting the filter allows the photographer to select an ND value from anything between two and five stops, saving them the bother of having to add filters to and them filters from their lens. (PolarPro also sells a stronger 6-9 stop edition of the VND filter, plus mist-diffusion Black Mist versions of both).

Because my review sample sits at the weaker end of the range for ND filters, I found that it couldn’t stop enough light to get truly long exposures outdoors on a bright, sunny day. Even at its highest 5-stop setting, and with my camera at its lowest ISO setting, a shutter speed of anything longer than a second resulted in a blown-out, overexposed image. So, if you want to shoot multi-second daytime exposures on sunny days or in bright landscapes (like snowfields), you’ll want to have the 6-9 stop filter to hand. If you’re feeling flush, buying both filters provides a wide stopping range.

On more overcast days, at night or indoors, however, the two to five stop range feels very usable. Even during the day, it allowed me to set a wider aperture than I’d normally be able to use for video, resulting in a shallow depth of field with background bokeh while maintaining an ideal shutter speed (of roughly double my frame rate, as the rule of thumb suggests).

The filter glass is extremely clear and neutral, although it does appear to add a very slight warm color cast when compared to shots with no filter attached. I couldn’t spot a single incidence of ghosting or chromatic aberration, however – two issues that can plague cheaper filters. And it doesn’t seem to affect the sharpness of images at all, which is what I would expect of a filter in this price range.

I also encountered no vignetting when shooting with a wide-open aperture at my lens’ widest field of view (12mm on a Micro Four Thirds camera, equivalent to 24mm on a 35mm or full-frame camera). PolarPro claims the filter exhibits no vignetting right down to 16mm, but I wasn’t able to put that to the test myself.

I also noticed that a small amount of additional contrast could creep into shots as I moved up the ND stop range. That’s a side effect of the variable ND filter design, I think – VNDs require polarized glass to achieve their variable effect, and that will affect the final image slightly. If that’s a no-no for you, you’ll need to use regular, non-variable ND filters instead.

While performance is strong, build quality might be even better. I was sent a 67mm filter to review (it’s also available in 49mm, 77mm, 82mm and 95mm sizes), and used a step-up ring (also by PolarPro) to fit it to the 62mm thread on my Panasonic 12-60mm F2.8-4.0 lens. Both the filter and ring screwed on smoothly and securely, with no awkward threading.

The combined case and lens cap (known as the Defender 360) makes fitting even easier – and ensures greasy fingerprints stay well away from the filter glass. The cap features two parts, one metal (aluminum to be precise) and one rubber, with the rubber element gripping around the filter’s frame so that you can, with a twist, add or remove the filter from your lens. When not in use, the filter sits inside the rubber part while the metal screws back on over one side to keep it safe. It’s an ingenious piece of design.

The filter itself feels beautifully precision engineered. The machined ridges or knurls on the edge give your fingers plenty to grip onto, while the subtle 'click' expressed as each ND stop is reached is welcome (and useful) feedback. Of course, some users might prefer a completely smooth turn, particularly videographers who want to adjust the stopping value while rolling the camera. It’s something to note, but I personally found it a clever design touch.

And, while this is a subjective thing, I think the PMVND II looks really classy too, with its two-tone black and brass finish. It’s hydrophobic too, with water beading and running off the glass easily.

Overall, I’m hugely impressed by the quality of the PolarPro VND Filter Peter McKinnon Edition II. Yes, it’s expensive – but it’s also thoughtfully designed, impeccably constructed, and works exactly as a variable ND filter should. If you’re looking for an ND filter to expand your creative repertoire, this 4-in-1 champion should certainly be on your radar.

PolarPro VND Filter Peter McKinnon Edition II: Price and availability

The PolarPro VND Filter Peter McKinnon Edition II is available now worldwide, priced at around $150 / £150 / AU$260 for the 49mm size or around $250 / £240 / AU$450 for the 67mm, 77mm, 82mm and 92mm sizes.

The filter is available in two ND stop ranges: 2-5 (which I'm reviewing here) and 6-9, with both models additionally available in a Black Mist version designed to soften highlights for a different look.

These are high prices for ND filters, but I think the quality and adaptability of the PMVND II makes it well worth the price to the right buyer.

Ulanzi GlideGo Travel Tripods: two-minute review

When you think of the humble tripod and all of the variations available, it’s difficult to imagine that a slightly different take on the classic three-legged design is possible. But Ulanzi has done just that with the Ulanzi GlideGo Travel Tripod and GlideGo Video Tripod.

Before getting into specifics, these two tripods are exactly the same, except for the head, with both being built around the same legs and basic ball head design; it’s the video model’s fluid pan and tilt movements alongside the handle that differentiate.

Oh yeah, and there's even a craftily hidden tool kit in the handle for adjusting the tripod. This head makes the video model slightly taller and heavier than the standard model, but the movements it allows for are impressive.

Both tripods also feature an articulating center column, which is rare for travel tripods, and this provides the opportunity for you to position the camera at many different angles. Further to this, the video version can achieve gimbal-like movements thanks to this feature, alongside 360-degree pan mechanisms on both the centre column and the head.

I love this feature and the creative camera angles and movements it allows for, which is something I’ve not seen with a tripod before, especially a video travel tripod. The head on this tripod features a fluid pan and tilt design that provides smooth movements without judder, which is essential for video.

One video tripod feature that is missing, however, is a levelling base; these are used to level the tripod head without the need to level the legs.

The way around this simply comes down to the fact that the video features of the head are built onto a ball head with the pan mechanism above the ball joint. This cleverly and effectively mimics the effect of a levelling base, while also providing fast set-up in a lightweight and highly portable travel tripod. Then there are some 1/4in and Arri mounting threads for attaching accessories.

These are tripods where the head itself is an integral part of the overall package and can’t be changed. It’s essential to be aware of this because the head becomes an even more important part of the purchasing decision than a tripod where the head can be changed. That said, the two head options do work extremely well and avoid camera slippage thanks to the clip lock that secures the ball joint perfectly.

I’ve not seen this design on a ball head before, and it’s more effective than low-end and mid-range ball heads that use the traditional locking knob/dial. The GlideGo tripods use Ulanzi Uka and F38 tripod plates rather than Arca Swiss, so you can’t use L-brackets with the heads unless the L-bracket has a 1/4in screw thread. There is, as with most ball heads, a notch allowing you to position the camera in portrait format, so you can shoot vertically.

The tripod plate uses a locking system where you push it into the head to engage the lock, push the button to the side to lock the button and then slide and push the button to release. This is admittedly much quicker and easier to use than a knob-style lock, although I can’t say whether it’s better or worse – it’s simply another approach that works and is a pretty neat way of locking and releasing.

The overall build quality of the two tripods is excellent, with four carbon fiber leg sections that provide an impressive level of rigidity and support, especially considering the narrow diameter of the thinnest bottom section. Legs are secured by clips rather than twist locks, and I found them to be fast, reliable and positive in use when working with both tripods.

The standard ball head version offers a height range of 16.1x72.4in / 41-184cm and weighs 3.44lbs / 1.56kg. The video version provides a height range of 17.3x73.6in / 44-187cm and weighs 3.88lbs / 1.76kg. Let’s just forget the numbers for a second and put it into context. This means that you can position your camera at over six feet with these tripods, which is high for compact travel tripods.

Both tripods have a max payload of 39.68lbs / 18kg, which is slightly misleading because this figure refers to the legs, while the head has a maximum payload of 11lbs / 5kg. This is still a commendable payload that can comfortably support the vast majority of camera and lens combinations, but a far cry from the headline figure.

Moving back to the articulating centre column, which is one of the defining features of the tripods, this also offers a telescopic function. This is where the articulating section is hidden within a vertical section until lifted out, and the outer section can then be left in position or raised to increase the height of the tripod.

There’s a useful hook at the bottom of the outer section of the tripod to add weight and stability when required, alongside a smaller hook on the inner column to add counterbalance if and when required.

While this is all great when finding angles, viewpoints and increasing the height of the tripods, it does mean that you can’t splay the legs to articulate the centre column at a low angle. Instead, you can keep the legs at their ‘standard’ angle and articulate the inner section of the centre column downwards. This means the camera is upside down, but you can shoot at low angles. It’s strange, but to be fair, it works.

Ulanzi GlideGo Travel Tripods: Price and availability

The Ulanzi GlideGo Travel Tripod and GlideGo Video Tripod were announced on 28 July 2025 and can be ordered directly from Amazon, the Ulanzi website and online photographic retailers, so they’re easy to get hold of.

Ulanzi is a photo accessory company you’ve probably come across, since there are many Ulanzi products available on Amazon. The company is well-known for its low-cost accessories that are manufactured to a high standard, and although the GlideGo tripods are priced similarly to bigger brands, they are still fairly and reasonably priced based on features and quality.

The JJ05 GlideGo Travel Tripod costs $269 / UK£300 /AU$359, while the JJ06 GlideGo Video Tripod is slightly more expensive at $299 / £320 / AU$389. The tripods come with carry cases, and the video tripod even has a handy toolkit hidden away in the tripod handle.

NiSi V7 with True Color NC CPL: two-minute review

When it comes to square filter holders, they’re surely all the same, aren’t they? In terms of basic design, they are, but build quality, functionality and value are another matter. For me, the NiSi V7 with True Color NC CPL is one of the best professional 100mm filter holders available, with an impressive performance that belies its attractive price.

100mm filter holders are typically used with lenses as wide as 15mm full-frame (or 10mm for APS-C). For lenses wider than this, you’ll need to move up to a cumbersome and painfully expensive 150mm square filter system.

150mm filters are also so large that they simply look ridiculous, and I have chuckled watching other photographers on location with me wrestle with their window pane-sized filters. But I digress.

The advantage of the Nisi V7 kit, like many 100mm filter holders, is that you can use up to three square filters at once alongside a polarising filter. So, that’s ND graduated filters, ND filters, color correction filters and special effects filters. Are three slots overkill? Definitely not – I often require all three slots when shooting in tricky lighting conditions while controlling exposure times.

One thing that I love about the NiSi V7 kit is that you get four adaptor rings, which means you can use the holder with four filter thread sizes straight away. These include 67mm, 72mm, 77mm, plus the main ring which has an 82mm thread. This covers the vast majority of landscape photography lenses, plus you can also buy adaptor rings for other sizes separately if you need them. For example, I own a 62mm ring that allows me to use square filters with my macro lens.

The V7 filter holder isn’t really suitable for smaller lenses with smaller filter threads, say in the 39mm to 67mm range. For example, I own some small Fujifilm prime lenses, plus some Micro Four Thirds lenses, for which the NiSi M75 II with True Color NC CPL is a better fit. The downside with this smaller holder only is that it only has two filter slots alongside the rear-mounted polarizing filter, rather than three.

Build quality of the V7 kit is excellent and the overall design is reasonably compact. The holder is a CNC-machined single block of matte black coated aeronautical aluminum, with three plastic filter holder slots screwed onto the front. The polarizing filter screws into the main ring, locking in place at around a 10-degree turn, while the holder clips onto the main ring and can be locked in place to avoid detachment of the two parts.

The main ring is also an 82mm adaptor ring, and is attached to the smaller adaptor rings when a smaller thread than 82mm is required. Practically speaking, these are best attached to the lens before the holder is attached. The polarizer can be rotated using a couple of small dials on the rear of the main ring. You can also use any 100mm square filters with this holder.

The advantage of the rear positioning of the polarizing filter is that the filter holder doesn’t vignette with lenses as wide as 15mm. NiSi even says that the Nikon Z 14-30mm f/4S doesn’t vignette at 14mm, although I haven't tried that lens with the holder. The rival LEE Filters LEE100 Polarizer mounts at the front, thereby creating a vignette with ultra wide-angle lenses – meaning Nisi has the advantage in this regard.

Unlike cheap polarizers, the supplied True Color NC CPL also produces clean images with no color casts at different rotations, which is exactly what you want.

In my experience, some filter holders can also be too tight, making it hard to slot filters in and out, to the point that this can risk accidental damage.

The V7, thankfully, provides just the right amount of resistance that filters are secure, but they’re easy enough to slot in and out of the holder when it’s attached to the front of your lenses.

The downside to a system like this, however, is that a set of filters and the holder take up space in your kit bag and can weigh more than other types of filters.

As magnetic and stackable filters are growing in popularity, you may be wondering what place there is for larger, heavier and more expensive square filters. The simple answer is ND grads. With square filters, you can get everything as right as possible in-camera, including the sky exposure.

With magnetic filters, the price you pay is no ND grads, so while you get a polariser, NDs and other types of filters depending on the kit, you have to shoot HDR to maintain sky detail. That naturally means you have to take more shots and spend more time at the computer editing. For me, square filters remain the optimal option for landscape photography.

NiSi V7 with True Color NC CPL: key specs

NiSi V7 with True Color NC CPL price and availability

The NiSi V7 with True Color NC CPL costs $259 / £199 / AU$389, which is an incredible price considering what’s included in the kit: a Filter Holder for three 100mm filters and a CPL, an 82mm main ring with polarizing adjustment, a True Color NC CPL (removable), three adapter rings (67/72/77), a soft case and a V7 Lens Cap.

To provide a point of reference, the LEE Filters LEE100 Polarizer filter alone costs as much as the NiSi V7 kit.

There are V7 kits available that also include several filters and offer excellent value for money compared to purchasing separately. The NiSi Starter Kit – V7 – 100mm Filters costs $499 / £345 / AU$849 and includes most of the above, a few additional accessories, a 3-stop medium GND and a 10-stop ND filter.

If you already own 100mm filters and would simply like a new filter holder, the NiSi V7 with True Color NC CPL is perfect for you. If you’re getting started with 100mm filters, I’d recommend the NiSi Starter Kit – V7 – 100mm Filters or one of the other kits that come with filters, because you will save money and have several filters to use from the get-go.

NiSi square filters themselves are expensive. They’re optically fantastic and made of high-quality optical glass, but expect to pay in the region of $245 / £95 /AU$279 per filter. The glass used is much better than traditional resin square filters in many ways, but they do cost more.

Insta360 Mic Air: two-minute review

Following in the footsteps of DJI, Rode, Saramonic, Hollyland and more, Insta360 brings us the Insta360 Mic Air, a compact, inexpensive wireless microphone designed with video creators in mind – particularly those who use the Insta360 X5 or Insta360 Ace Pro 2 action cameras.

The button-sized, ultra-lightweight Mic Air transmitter (aka the TX) can connect wirelessly to either of the above Insta360 cameras, either replacing or teaming up with the on-board mics. The idea is that it adds an instant upgrade to sound quality, offering 48kHz / 24-bit audio, optional noise reduction, and a furry attachable shield to cut down on distracting wind noise.

Having tested the Mic Air on a typically breezy day on the English coast, I’m very happy with the results. With the windshield carefully attached, the noise from occasional strong gusts was completely removed, as the video below illustrates. I say “carefully” because Insta360 has opted for a slightly unconventional method for attachment: the shield is mounted on a rubber ring that slips over the sides of the TX, and some care must be taken to ensure that it’s sited directly above the mic grille.

There’s also a form of noise reduction available, accessed by double-tapping the TX’s power button. It’s fairly effective, helping negate background drones and hums without overly distorting the final audio. You can also adjust the mic’s gain in the X5 or Ace Pro 2’s menu screens, and there’s an on-screen indicator while you’re recording to give you an at-a-glance view of the current gain.

Connected directly to the X5 or Ace Pro 2, the Mic Air has a short range – about 30 to 50m. But add the receiver (or RX) and things get a lot roomier, with the theoretical range going up to 300m (the real-world results are less thanks to interference and obstructions).

Note – at launch, the Mic Air is compatible with the X5 and Ace Pro 2 only. Insta360 says a firmware update is coming for the X4, while the Go 3 / 3S won't be compatible with it. The X3 and the Ace Pro aren't compatible either, but could be further down the line.

The receiver, which is also tiny and lightweight, has a USB-C connector that enables you to plug it into smartphones, tablets, laptops and other products, such as Insta360’s Flow range of smartphone gimbals. It then establishes a wireless connection with the transmitter, so that when you hit the record button on your device the audio recorded comes from the transmitter rather than your device’s own microphone.

I still use an older iPhone model with Lightning, so I wasn’t able to test this method on my smartphone (Insta360 has told me that a Lighting version is a definite possibility for the future). While I understand the decision not to offer a Lightning option at launch, it does leave some people out of the loop, as does the lack of a 3.5mm output for connection to cameras. Some other small, affordable mics, like the DJI Mic Mini and Fulaim X5M, offer wider connectivity.

I did, however, put the Insta360 Mic Air through its paces hooked up to an Android tablet, and found the audio quality a huge improvement over that offered by the built-in mic. You don’t have to use it just for video capture, either – it would also improve the quality of voice notes and recordings, Zoom calls, and anything else that requires the use of a mic.

One thing Insta360 has done really well with the Mic Air is offer a variety of mounting options. In the box there’s a button magnet, which lets you attach the TX to thin clothing, as well as a clip magnet that can grip onto collars, lapels, bag straps and even cap brims. I’ve seen those with virtually every wireless mic I’ve reviewed, but here there’s also a magnet pendant, so the user can wear the TX around their neck. It’s nice to have that extra option.

The magnet also comes into use when recharging the TX battery, locking it into position on its charging plate. The charging plate uses USB-A, which surprised me a little in 2025 where USB-C is ubiquitous, but I doubt many people will struggle to find somewhere to plug it in.

On the subject of the battery, the TX offers about 10 hours of use on a full charge, which is a little less than the DJI Mic Mini’s 11.5 hours, but still very respectable.

Insta360 Mic Air: price and availability

The Insta360 Mic Air is available now, with two options available. For buyers who own an Insta360 X5 or Ace Pro 2 camera and just need a mic transmitter to connect to it directly, the Mic Air Transmitter package costs $49.99 / £49.99 / AU$89.99. It comes with a single TX unit, charging base, button magnet, magnet pendant, clip magnet, windshield and carry case.

For those in need of more flexibility, there’s the Insta360 Mic Air (1 TX + 1 RX bundle), which includes all of the above plus one USB-C Receiver unit that can plug directly into smartphones, tablets, computers and more. This costs $69.99 / £69.99 / AU$129.99.

Insta360’s pricing seems very fair to me, although recent price drops have seen the DJI Mic Mini (1 TX + 1 RX) bundle fall to just $89 / £59 / AU$199, or £78 / $139 with a Lightning adapter. That’s probably a better deal than Insta360’s, if you can find it.

PolarPro QuartzLine ND filter: two-minute review

In photography, we often want more light. It’s why people seek out larger sensors and wider apertures in their cameras and lenses – in order to capture a greater amount of light in a shorter space of time. That’s brilliant if you want a fast shutter speed to freeze the action – but what if you want to use a slower shutter speed, in order to capture the motion blur of a car racing past or turn a raging river into a smooth, silky ribbon of blue?

Achieving a slow shutter speed, particular on a sunny day, can be tricky – which is where ND filters like the PolarPro QuartzLine range come in. Available in a wide range of strengths, these circular filters screw onto the front of a camera lens and reduce light transference without affecting color rendition. At least, that’s the idea.

PolarPro sent me four ND filters to test, all in 67mm thread size (they’re also available in 77mm and 82mm), in ND8, ND16, ND64 and ND1000 strengths. The ND8 filter drops light input and increases exposure time by three stops; the ND16 four stops; the ND64 six stops; and the ND1000 filter 10 stops. Obviously, having a set like this in your camera bag would be handy if you want to cover every eventuality – but it’ll be mighty expensive too.

Each filter comes with its own hinged hard carry case and microfiber cleaning cloth, emphasising their premium positioning. The cases are hard plastic, but have a fetching brushed metal finish and magnetic closure, and each is helpfully labelled with the thread size and ND value, to reduce the time it takes to pull out the right one from your bag.

The filters themselves are well crafted and beautifully solid, so it does at least feel like that money is going somewhere. Made of brass and aluminum (and with a distinctive brass-colored finish), they’re reassuring tough, with pleasingly chunky ridges that gave me plenty of grip whenever I was attaching or detaching them from my Panasonic Lumix GH6’s lens (I used a 62mm to 67mm step-up ring, also made by PolarPro, in order to do so).

The brass frame construction should keep the screw threads in good shape too, in theory – so these filters should be fitting smoothly for many, many years to come. I found them very easy to fit, but you’d expect that from new filters. They also feature front threads, allowing other filters and attachments to be fitted over them.

The glass, dubbed Cinema Series Glass by PolarPro, is made in Germany. A series of coatings purportedly eliminate color shift (any sort of color cast being added by the filter), and PolarPro also claims its ultra-low refractivity keeps the effects of the light passing through so minimal that it can fully resolve sensors with up to 400MP resolution. The coatings add anti-scratch, anti-oil and hydrophobic qualities too.

My Lumix GH6’s sensor is just 25.2MP, so doesn’t really help in putting the refractivity claims to the test, but in terms of color shift I can say I’m impressed. Even the most powerful filter of the four I was testing, the ND1000, doesn’t add much of visible color cast to images – but when closely comparing test shots without the filters to those with, there is a slight warm tint visible in the filtered images.

I wouldn’t call this a huge drawback, particularly as I think anyone spending this much money on ND filters probably has some experience in post-processing and editing photos. It’s nothing that can’t easily be fixed in Lightroom or similar, and most observers wouldn’t even notice it unless they were looking, but it’s definitely present.

Using the filters, I was able to capture long exposures (10 seconds or more) on bright, sunny days by the sea. These photos smoothed out the motion of the waves and made the surface of the water more transparent to give my images a much more dream-like quality. They would have been completely impossible to take without an ND filter, as too much light would have entered the camera and blown out the image.

I was also able to use the filters to aid my videography by helping me to shoot video with a wider aperture (i.e. for a shallow depth of field) or slower shutter speed (for more motion blur). I did find this a little more challenging at points, as it involved swapping between filters a little too often – and it’s times like that when a variable ND (or VND) filter feels invaluable. These allow you to adjust ND strength by twisting the filter, offering a much more immediate solution. I’m also currently reviewing PolarPro’s own PMVND Edition II filter with a 2-5 stop range, so look out for an in-depth review of that soon.

While PolarPro QuartzLine ND filters are certainly expensive, I was thoroughly impressed by their premium construction, glass quality and general usability, and wouldn’t hesitate to use them in my own landscape photography and videography.

PolarPro QuartzLine ND filter: price and availability

In the US, PolarPro QuartzLine ND filters cost the same price, regardless of their thread size and filter strength at the PolarPro store. Whether you pick 67mm, 77mm or 82mm threads, or the ND8, ND16, ND64, ND1000 or ND100K strengths, every filter costs $99.99. Simple and, in my opinion, good value for money – particularly given that you also get a hard storage case and cleaning cloth with each filter.

In other countries, the price can vary a lot more. In the UK, for instance, the filters seem very expensive in comparison to US pricing, and thread size and ND value seemingly have little bearing on the cost – i.e. at Amazon UK, the larger thread sizes are sometimes cheaper than the smaller ones, where logic would dictate the opposite. It’s a slightly confusing situation, with some retailers offering decent discounts while others charge the full whack.

How I tested the PolarPro QuartzLine ND filter

• One week of use
• Tested with photography and video capture
• Used with Panasonic Lumix GH6 camera

I tested these PolarPro QuartzLine ND filters over the course of a sunny summer's week by the sea in southern England – an ideal time and place to put this type of light-stopping filter through its paces. I tested four filters in the range, fitting them onto my Panasonic Lumix GH6 camera (with the help of a step-up ring) to capture both still photos and video, comparing the results against shots captured without the filter.

Heipi 3-in-1 Travel Tripod W28S: two-minute review

Ask around, and most enthusiast photographers and creators are familiar with the accessory maker Peak Design, but newcomer Heipi? Nope.

Well, I have a welcome surprise – Heipi's carbon fiber 3-in-1 Travel Tripod W28S beats the Peak Design Travel Tripod in just about every regard, plus it's cheaper too. Three-Legged Thing's Punks Brian 2.0, however, provides stiffer competition for standard use – I explain why, below.

The W28S replaces the W28 – which I described as one of the most relevant and best travel tripods today in my in-depth review – delivering several refinements for a virtually complete and highly versatile three-legged support, in three ways.

Its 3-in-1 credentials cover regular tripod support for camera gear, the ability to support a phone instead via a clamp that's hidden in the integrated ball head, plus a generously-sized removable mini tripod, which is nestled inside the main legs, and which doubles up as a center column – the novelty of this feature hasn't worn off in this second-gen model.

Given that the main legs can tuck inside the mini tripod legs when you're done, there's no wasted space and the Heipi 3-in-1 is able to pack away more compact than most, plus it comes supplied with a snug-fit carry case.

There are limitations though. I'd hesitate to mount particularly large and heavy gear – although that's true of all travel tripods – and the Heipi tripod's maximum height is bettered elsewhere. Also, despite its 3-in-1 party tricks, there's no monopod built into one of the legs. Nor can you swap out the supplied ball head for a fluid head, which would provide smooth panning movements for video.

If none of the above are dealbreakers, though, then Heipi's latest travel tripod is the complete package, with some unique features.

It's carbon fiber build quality is top-drawer, while improved leg locks are easier to lock-off and unlock than before. Also, they lock-off with even distribution on the leg sections (rather than a clamping lock), which reduces lateral movement between sections.

The addition of a bubble-level in the base is a neat touch, even if you can't see it properly when the center column is tucked away.

Heipi also offers handy extras for accessory-laden users, such as clamp arms, which easily screw into the mini tripod legs via a 3/8-inch screw. The arms Heipi supplied to me for this review can support accessories such as an external monitor, and can even work with Heipi's optional phone clamp, so you can support a camera and phone simultaneously.

I've been able to switch between using a phone and a mid-range mirrorless camera with moderate size lens, with ease. Panning movement? No problem, unlike the Peak Design which is locked off.

Even the design of the mini tripod, which easily rests on a table top for vlogging and is impressively sturdy with a 11 lbs / 5kg max payload, has been improved. The last version felt like it sacrificed ease of use for versatility, because it was stiff to extend and put away compared to a regular center column.

Now the mini tripod slides up and down much more easily, and when fully removed it even offers multiple leg angles to work from for a variety of shooting angles, including close to the ground.

It can also be reversed and locked-off upside down in the main legs in order to shoot from lower angles. Put simply, the mini tripod is one of the most sophisticated of its kind.

With camera gear generally getting smaller and lighter, and many creators using their phones as much as 'proper' camera gear, the case for the travel tripod grows as the case for bulkier supports diminishes.

And of all the many travel tripods I've reviewed, the Heipi 3-in-1 Travel Tripod W28S is the one I come back to most often – I reckon this is the best tripod for most people.

Is Heipi's travel tripod perfect? No. There were times that I wished it could work from a higher level than its 59in / 150cm maximum reach (with the center column fully raised).

However, given it packs away with a tighter diameter than most and to just 17.7in / 45cm in length, while it weighs just 3lbs / 1.35kg (with ball head included), I'm happy to sacrifice any extra reach.

And one party trick it lacks, which you can find in many alternatives, is the ability to remove one of its legs for used as a monopod.

If you can live with the few limitations mentioned above, then the Heipi 3-in-1 Travel Tripod W28S will be the most versatile tripod you've ever used, complete with a high-quality and lightweight carbon fiber build, plus tiny pack-away proportions.

If you want a lightweight support for a variety of camera gear, Heipi would be my first recommendation.

You can discover more about the W28S's design and features in my W28 in-depth review, the two share much in common besides some of the design tweaks mentioned above.

How I tested the Heipi 3-in-1 Travel Tripod W28S

• I've used it over several months
• I've extensively used its 3-in-1 features
• I've attached various mirrorless cameras and smartphones

I've had the Heipi 3-in-1 Travel Tripod W28S for months and it has been my go-to camera gear support during this period.

It has ably supported beginner, mid-range and pro mirrorless cameras, although I've drawn a line at the larger sports-focused bodies and bulky telephoto lenses.

I've also used the phone clamp, attached a variety of smartphones the largest of which was an iPhone 15 Pro Max, plus tried out optional extras including clamp arms for an external monitor.

The mini tripod has had equally thorough testing as the main tripod legs. Generally I've used the gear in fair weather, but it has also withstood moderate rain and use on sandy beaches.

Peak Design Pro Tripod: two-minute review

Peak Design’s tripods have a couple of unique design features. One is the leg design, which is not tubular but has a six-sided cross section with an inner edge that fits straight up against the center column, with no gaps. The center column is thinner than most but also has a six-sided cross section for the legs to fit neatly against the legs when folded. This non-tubular construction does seem to give both the legs and the center column unusual stiffness.

The other unique feature is a low-profile ball head with no protruding locking nut. Instead, it’s clamped with a rotating collar, and another, just above locks and releases the compact Arca Swiss compatible camera plate.

This low profile head design means that the original Peak Design travel tripod does not have to have its legs rotated 180 degrees from their folded position before you can use it. The low height of the ball head means that you can simply fold the legs in and pack it away without any complicated manoeuvers.

These design features made the original Peak Design Travel tripod very different to anything else. Now Peak Design has taken those same design concepts and scaled them up into a Pro version designed for serious professional use.

In fact, there’s not one Pro tripod but three. The regular Pro tripod is the one I spent most time with for this review, but I also got to try out the Pro Lite and Pro Tall variants. The Pro Lite is almost the same height and folded length of the regular Pro Tripod, but has a lighter construction for easier portability. The Tall version has longer leg sections and can even reach eye level for tall people without any center column extension – it exceeded my eye level!

The new Pro tripods aren’t just bigger and more substantial than the original Travel Tripod – they have a new Pro ball head that’s larger and more substantial than the original, plus it has a neat ‘inverted’ design so that the pan axis is above the ball not below it. This means that you can level the pan axis for panning shots and panoramas without having to fiddle around with the leg lengths. It’s not a huge range of adjustment but it might be all you need.

For more extreme pan axis adjustments, or if a lot of your work is video, Peak Design has you covered. There are two new ‘mods’ to go with these tripods: one tilt head for video work, and the other a leveling bowl which you swap out with the standard center column, and which has a regular head attachment screw so that you can use your favorite video head if you want to.

I love the original Peak Design Travel Tripod, so do the new Pro tripods leave me just as impressed? Yes! It is, literally, just like using scaled up versions of the Travel Tripod. The carbon fiber legs feel just as smooth and warm to the touch, the leg clamps are just as quick and positive, and because these Pro tripods have four leg sections rather than five, they’re a little quicker to set up.

The new Pro ball head is terrific. It’s big and chunky, it locks tight and it doesn’t add a whole lot to the tripod’s height when you’re packing away. As before, there are no protruding knobs or levers to get in the way either.

Peak Design’s use of a rotating collar to lock the QR plate does take a little getting used to. The head has two collars in close proximity and at first it can be a struggle to remember which does what and how they work.

The new Pro head, though, feels absolutely rock solid, and it’s with the pan and tilt mod that it gets really clever. All you need to do is take out the regular Arca Swiss plate and slot in the pan and tilt add-on for a proper fluid pan and tilt action.

There’s an extending panning handle which is stowed against the side of the head via a magnet (Peak Design loves magnets) and can be quickly screwed into the head ready for use. It sounds like a kludge, with one head mounted on top of another, but it absolutely isn’t. It looks like it was made to work this way, and feels like it too. The tilt axis is sprung, by the way, so if you use a longer camera plate you should be able to balance it up fairly well for light and controlled tilt movements.

The center columns on these tripods are longer than the one in the original Travel Tripod, which is useful, but even though they’re fixed with a small-looking locking knob, they lock down really tight and with no flex.

You can also get spiked feet but these are an optional extra, nor does it seem like Peak Design includes a phone clamp with these tripods, so that will be a paid extra too. It kind of makes sense because these Pro tripods are overengineered for phone use anyway. If you do get the phone mount, it will still slide up into the base of the center column for storage. Here, Peak Design has stuck with its slightly complicated pull-and-twist hook release which is easy when you’ve learned how it works but can be annoying at first.

So that’s a quick tour of the Peak Design Pro Tripods, but which is the best one to get? That’s quite tricky because they are somewhat similar, both in size and price. The standard Pro tripod is expected to sell for $899.95 when it goes fully on sale in November 2025, the lighter Pro Lite will be $799.95 and the Pro Tall will be $999.95. I haven't seen prices for the UK or Australia yet.

Personally, I wouldn’t go for the Pro Lite. I can understand the reasoning – it’s a slightly lighter, slightly cheaper alternative to the regular Pro model – but it’s not a lot smaller and I think I’d rather just pay the extra for the thicker legs of the Pro model. The Pro Tall is interesting, though. If I was 6ft tall and didn’t like using center columns, I would go for this one. It’s definitely longer when packed away, but all of these tripods are too long to fit inside a backpack anyway and would end up strapped to the outside. Besides, for those times when you didn’t need the extra height you could just extend three leg sections not four, for even more stability.

How I tested the Peak Design Pro Tripods

• Operational speed and efficiency
• Stiffness and rigidity
• Ball head operation
• Effectiveness of add-ons

I had just two weeks to try out the Peak Design Pro tripods because loan stocks were in short supply and shared between many different reviewers. However, I know the original Peak Design Travel Tripod very well and I review tripods as part of my work, so I already had a list of what I was looking for and expected from these new Pro tripods.

I particularly wanted to test the speed and ease of deployment and was pleased to find it was just as slick as with the original Travel Tripod but quicker, thanks to the 4-section legs and larger leg clamps. I also wanted to check if the excellent stiffness of the original Travel Tripod had scaled up to these new, bigger sizes, and it has. I don’t remember any other tripods I’ve tested with more torsional rigidity and lack of leg flex than these.

I was also keen to check how the new Pro Ball Head worked. The original was good but quite small and fiddly. This one is much better. Not only does it clamp tighter and hold heavier loads better, the inverted ball design makes levelling the camera for panning shots so much easier.

Lastly, I spent some time trying out the Tilt Mod and Pro Leveling Base and came away impressed. The Tilt Mod fixes so well to the Pro Ball Head that they feel like a single (very smooth) unit and the Pro Leveling Base took a minute or so to swap out with the regular column but lets you use your own tripod head.
