Nikkor Z DX 24mm f/1.7: Two minute review

Nikon has taken some time to release the Nikkor Z DX 24mm f/1.7 Lens. It is the company’s first for its mirrorless Z-mount cameras with APS-C size sensor (Nikon calls this lens format 'DX'), the first of which, the Nikon Z50, was unveiled in 2019, a year after the first full frame Z mount cameras (which Nikon calls 'FX'). As I write this in 2023, there are now a total of three APS-C cameras in the system, with the retro-inspired Z fc and Nikon Z30 joining the ranks.

With the 'DX' cameras being some of the best beginner mirrorless cameras and appealing more to the entry-level market, it is logical that to date, all four of the Z-mount DX lenses are zooms, with focal length coverage from 12mm all the way to 250mm, plus fairly modest aperture settings. There is an obvious gap for prime lenses with large apertures, but up to now, this has been covered by using a full-frame Z-mount lens on DX-format cameras. 

Now, Nikon has introduced the Nikkor Z DX 24mm f/1.7 - a compact prime lens that provides roughly the equivalent field of view to a 36mm lens on a full-frame sensor camera, such as Nikon’s popular Z6 II or the Nikon Z8. However, it’s really best to think of this as a 35mm equivalent focal length lens, for all intent and purposes. 

The 35mm equivalent focal length is always a good place to start when you introduce prime lenses. The field of view offers a natural feeling, close to that of human vision, but allows some periphery so that images and video created don’t feel too close and tight. The f/1.7 aperture setting offers an equivalent depth of field to an f/2.5 full-frame lens, so it is a nice combination for creating shallow natural-looking images and depth of field. 

Externally, there is little to talk about on the lens. It has a very basic design with a small section of barrel, with most of the circumference being taken up by a ribbed manual focus ring. Besides the lens designation and branding, there is little else to note. 

It is as small and light as you would expect, weighing just 135g and measuring 70mm x 40mm. It has a small 46mm filter thread, and with the front lens element being much smaller than the barrel, the included HN-42 lens hood cones slightly inward to prevent light from hitting the lens element at acute angles. Overall, the build is best described as being ‘neat’.

Internally, the construction comprises 9 elements in 8 groups, with two aspherical elements, and the aperture features seven rounded blades. The only real item of note looking at the specifications is that the minimum focus distance is a reasonably close 18cm, which makes the lens an interesting choice for close-up work, particularly for those who are shooting video.

I had the Nikon Z fc for my test of the 24mm f/1.7 lens, and they made a perfect pair, being pocketable if you happened to be wearing a parka jacket with huge pockets. Still, for the rest of us, it would slip very easily into small sling bag, making the combination ideal for a weekend away. 

While away for a few days and also shooting a little bit closer to home. I found the Z fc and 24mm f/1.7 combination snuck into a small sling bag that was actually designed to hold a tablet and a few accessories, so it was a nice size to carry around. Photographing my kids playing, as well as general snaps of animals at a petting zoo and some landscape shots in less-than-ideal lighting, the lens performed well. The autofocus of the lens and camera kept up – although it wasn’t lightning-quick, I also wouldn’t expect it to be. 

What it did do is live up to my expectations; it was a great carry-around lens that, with a 35mm equivalent lens, gave a similar field of view that I am used to having on a smartphone, but offering much better image quality and sharpness that I would ever get from even the latest phone. 

Nikkor Z DX 24mm f/1.7: Price and release date

The Nikkor Z DX 24mm f/1.7 Lens costs £289.99/US$279.95/AU$499 and is on sale now. As it it is the first Nikon DX prime lens, there is little to compare it to within the range. The most obvious alternative lens from within the range is the NIKKOR Z DX 16-50mm f/3.5-6.3 VR lens, which should prove to be a great all-purpose lens, although it lacks the larger f/1.7 aperture for low light shooting. It costs £329/US$309.95/AU$449.

Sigma produces a series of 3 lenses DX lenses for the Nikon Z, the same lenses available for most other APS-C and Micro Four Thirds mounts. Of these, the Sigma 30mm F1.4 DC DN is the closest match to the Nikkor 24mm f/1.7. The Sigma lens has a narrower field of view at 45mm equivalent lens, which, along with the f/1.4 aperture, makes it more suited to portrait shots but less useful as an everyday walk-around lens. It costs US$399 / £349/ AU$699.

Nikkor Z DX 24mm f/1.7: Image quality

The beauty of a fixed focal length in this standard range is that detail is usually pin-sharp, and the 24mm f/1.7 is no exception. In the very center, details such as hairs on animals – in the case below, a goat – are perfectly defined. 

There is impressive detail resolution, even when shooting wide open. However, it is at f/2.8 to f/4 that I found the sharpest of the aperture settings. There is some drop in quality towards the edges of the frame, but the quality is impressive, especially when the lens's size and price are considered.

I didn’t notice any chromatic abberation in my real-world images, but by shooting through trees into a bright, overcast sky, I could force the issue by overexposing slightly and then viewing the image at 400%. Then, I could see some magenta along the edges. No one in their right mind would do this, so rest assured chromatic aberration isn’t an issue, and again, there is in-camera correction.

There is some vignetting with the correction turned off. Shooting a brick wall as part of my testing (brick wall construction is not a hobby of mine), shots taken at f/1.7 had heavy vignetting in the corners that took a +100 adjustment in Adobe Camera Raw to correct. Stopping down to f/4, and the shading in the corners had gone. All that said, vignetting correction is just a few button presses away, and it gets rid of vignetting entirely, even at f/1.7, so unless you are an absolute lens purist, you don’t ever have to worry about it. 

Again, with curvilinear distortion correction turned off in the camera, some pincushion distortion is present. A quick shift of the distortion correction in Adobe Camera Raw to -6 straightened everything up, and the image looks virtually identical to the image straight out of the camera with the in-camera correction switched on.

The overall conclusion is to leave the in-camera corrections all switched on and shoot away quite happily, knowing the images will be virtually perfect.

How I tested the Nikor 24mm f/1.7 lens

I tested the Nikor 24mm f/1.7 lens by taking it away with me for a few days away. I used it on a Nikon Z fc and took various images, just as someone would take it with them on their travels. This included scenic images, shots of my children, shots of animals at a petting zoo, as well as some detail shots to test the close-up ability and to see what the background bokeh looked like. 

During the real-world testing of the lens, I used a variety of different aperture settings and focusing methods to see how the lens performed.

I accompanied these images with some test shots of a brick wall to test vignetting and curvilinear distortion, as well as the tried and tested method of looking for chromatic aberration by shooting an overcast sky through tree branches.

Two-minute review

Sony’s 50th full-frame lens, the FE 70-200mm F4 G OSS II, is a comprehensive update of the (almost) 10-year-old Sony FE 70-200mm f/4 G OSS stalwart. It’s part of a recent wave of smaller and lighter second-gen Sony lenses, in this case, it's 15% smaller and lighter than its predecessor, weighing 794g / 28.1 oz, and measuring 149mm / 5.8in long. 

Lens size is a big deal when you shoot with Sony cameras – they are smaller than most and can feel off-balance with a big chunk of glass on the front. I paired the 70-200mm F4 II with the Sony A7C R, which is one of the best travel cameras, plus the crop-sensor Sony A6700 (with which the lens focal length is increased 1.5x), and both cameras proved an excellent fit with the lens. 

If this mark II version of the lens was only smaller and lighter it could be worth an upgrade for that reason alone, but it’s also the beneficiary of a total redesign, which has given it sharper image quality, faster autofocus and next level macro focusing. Yes, it’s smaller, lighter, sharper, quicker and more versatile than the original, and one of the best Sony lenses around.

The 70-200mm lens is already a versatile focal length – my own Nikon 70-200mm F2.8 G DSLR lens was my most-used lens for many years for portraits, weddings and events, and also proved to be an adept tool for sports, wildlife, landscape photography and more. Sony’s 70-200mm F4 II happily works in these fields, but also adds class-leading macro focusing capability, up to 0.5x magnification at any focal length, with a minimum focus distance of 0.26m / 0.86 ft at 70mm, and 0.42m / 1.38ft at 200mm.

Add the 2x teleconverter with an unchanged minimum focus distance and the macro capability is doubled to 1.0x magnification – that’s 1:1 life size. I’m generally not a fan of teleconverters; even the very best soften the image and can affect color rendering. In fact, you can see the minimum focus distance in action, plus the color shift of the same scene shot with and without Sony's 2x teleconverter, in the sample images below. In any case, the 0.5x magnification without teleconverter beats any other 70-200mm lens and adds another string to the bow of this versatile zoom lens. 

This is also a well-made and complex lens, with customizable function buttons and no fewer than five switches covering features such as a focus range limiter (including a new macro setting), full-time direct manual focus, SteadyShot optical stabilization and a zoom-lock that fixes the lens in its closed position when not in use – otherwise the lens barrel extends when zooming. 

Sony also says its new linear XD focusing technology, comprising four ‘high-thrust’ focus motors, increases autofocus tracking precision, even while zooming, and ultimately achieves what is 20% faster focusing than in the 2014 version. 

Camera tech has moved on in the 10 years since the original 70-200mm F4, too, and when you use the 70-200mm F4 II’s new focusing skills with a Sony camera equipped with the latest Bionz X processor and AI-autofocus chip, focusing is super intelligent, quick and reliable. For this review, the 70-200mm F4 II and A7C R have given me lightning-quick and reliable autofocus for photos and smooth video autofocus. 

Sony FE 70-200mm F4 Macro G OSS II: price and release date

The Sony FE 70-200mm F4 Macro G OSS II lens costs $1,699 / £1,749 / AU$2,699 and includes a lens hood and removable tripod collar. It was available from August 2023. That's an understandable price increase given the improvements in this second-gen model, somewhere between the F4 original version, and the current pro-level Sony FE 70-200mm F2.8 II version. 

Sony FE 70-200mm F4 Macro G OSS II: Image quality

An array of advanced aspherical and extra-low dispersion elements suppress lens distortion and render sharp detail, while the 9-blade aperture produces what Sony describes as ‘exquisite full-frame bokeh’. 

You can see from my self portrait below (taken remotely using the Sony Creators' app, at the lens' widest possible F4 aperture) that bokeh is smooth with no aberration or onion-ring distortion, while the shape at F4 is fairly round in the center of the frame, yet distinctly cat-eye in the corners. I’ve included cropped areas of the picture for a better look. 

If I were to take the exact same picture under identical conditions with Sony's 70-200mm F2.8 lens instead, or a prime lens with an even wider aperture, then bokeh would appear larger, and most likely even rounder. For an F4 lens, bokeh is actually very pleasant, but portrait specialists would choose an F2.8 or wider for that 'exquisite' bokeh.

Flare is also really well controlled in this backlit scene, and I’ve included a different macro photo of a spider and its web (in the same gallery) with stronger backlighting, and flare is mostly absent in that example, too. The included lens hood helps to reduce flare in these kind of scenarios.

A close look at the detail in the eye of the same self portrait reveals super-sharp detail, right where it matters. This single portrait photo alone displays many excellent attributes of what is an impressive telephoto zoom, paired with a reliable autofocus system in the latest Sony mirrorless camera.

Cast your eye over a wide range of photos, some of which are included in the gallery below to show the breadth of subjects you can capture, and it's clear the 70-200mm F4 II is a highly capable all-rounder. Image sharpness is maintained from the center to the edges of the frame, there's virtually no barrel or curvilinear distortion (the 70-200mm lens isn't known for either), and even in the corner of woodland photos with bright background light punctuating the tree cover, there's virtually no chromatic aberration. Put simply, there's very little fault to pick at in this excellent lens.

The image quality disparity between the pricier and heavier Sony FE 70-200mm F2.8 pro lens and this second-gen F4 model has diminished somewhat and arguably the choice isn’t about overall image quality anymore – or even depth of field, because the F4 aperture gives an extremely shallow depth of field with a full-frame camera. Instead, it comes down to whether or not you need the extra stop of light, or particularly big bokeh.

Personally, I regularly rely on the wider F2.8 aperture for events and wedding photography in particular, where light is often dim. However, that Sony F2.8 lens is much heavier, and if you mainly shoot in daylight and would prefer a travel-friendly lens, then the F4 II is a no brainer.

Overall, the second-gen 70-200mm F4 lens is notably better - and more versatile - than its predecessor in almost every regard. The sting is the costlier list price, although it’s worth the extra money if you want a lighter lens better balanced with your Sony camera, together with its refined image quality and closer focusing.

How I tested the Sony FE 70-200mm F4 Macro G OSS II lens

I've had my hands-on the Sony FE 70-200mm F4 lens on several occasions, for short and extended periods of time. I used it extensively while I was writing my Sony A7C R review, in a generous variety of scenarios that allowed me to fully test its capabilities. 

At a pre-launch event I was able to test its close-up photography opportunities with the 2x teleconverter that increases its maximum 0.5x magnification to 1.0x. I've also happily used the lens for macro shots without the teleconverter at my own leisure. 

It's been attached to the travel-friendly A7C R and A6700 cameras, making for an ideal size-match, and I've shot everything from portraits to landscapes with it, plus low light sequences that push the lens' AF motors. I've also used it for general travel photography, for which this lens is a lovely companion.
