Nikon Nikkor Z 24-70mm f/2.8 S Pro Review - John Riley reviews the new Nikkor Z 24-70mm f/2.8 S Pro lens for full-frame Nikon Z mirrorless cameras.
| Nikon Z 24-70mm f/2.8 Pro in Interchangeable Lenses
Any new camera system, such as the Nikon Z series, needs lenses to support it and one of the most important is the high quality standard zoom. There are many fine 24-70mm f/2.8 lenses on the market, so the potential of Nikon's new Z system can perhaps be fairly judged by their new offering, the Nikkor Z 24-70mm f/2.8 S lens. This promises superb performance, so let's start off our look at Z system lenses and see if it delivers that promise, and indeed if it could tempt us into a new camera system.
Nikon Nikkor Z 24-70mm f/2.8 S Handling and Features
Weighing in at 805g, the lens fits well with the Nikon Z7 45.4MP full frame mirrorless camera provided for this review. There is extensive use of reinforced plastics, but the construction quality is excellent and all controls operate smoothly. The lens is dust and moisture sealed, almost a requirement with current lens ranges.
Starting at the front of the lens, the supplied petal shaped lenshood bayonets securely into position. Within this bayonet is a standard 82mm diameter filter thread. The front and rear elements of the lens are fluorine coated to repel dust, grease and moisture. The lens also features Nikon's new ARNEO and nano crystal coatings, offering a high degree of resistance to flare.
Continuing towards the camera body, first up is the manual focus ring, electronic in operation and also fully usable during AF to fine tune the focus position if desired. Focusing is down to 0.38m (1.25 feet) and gives a maximum magnification of 0.22x. Behind this is the zoom ring, clearly marked at 24, 28, 35, 50 and 70mm. The exact focal length setting can be seen in the small OLED display immediately behind. This display, similar to that seen on some Zeiss lenses, initially shows NIKKOR when first switched on, but then changes to show zoom position, focus scale with depth of field indication or aperture. Which function is shown can be selected using the DISP button just to the side of the display. At this point there is also an L-Fn button, which via the camera menus can be assigned to offer up to 21 different custom functions.
Returning to the OLED display, it is certainly useful from a lens testing perspective to be able to select the focal length accurately. It is also a very visible way of showing the aperture in use should this option be chosen. When we look at the distance/DOF option though, the practicality of this is limited. The DOF is indicated by a line that expands and contracts to show the range against the distance scale, but sadly that scale is so short and bereft of actual numbers that it is doubtful that it is actually much use. The principle though is spot on, and somewhat reminiscent of the manual version of this found on Rolleiflex TLR cameras as far back as the 1950s.
There is one final control ring, close to the camera body. This can be programmed to adjust focus, aperture or exposure compensation, depending upon how the photographer wishes to work. This could be useful when making quick adjustments. Just behind this ring we find the AF/MF switch. If a selection is made in camera instead, that will override the lens setting. So, for example, if the camera is set at MF then the lens will not autofocus on either setting.
Optical construction is 17 elements in 15 groups, including 2 ED (Extra Low Dispersion) and 4 Aspherical. There is a 9 bladed diaphragm with rounded blades, aimed to improve the bokeh of the images, the smoothness of the out of focus areas.
In terms of ergonomics, the lens is spot on and all the controls are perfectly placed. Rings turn smoothly, but firmly enough so that they are not prone to being accidentally moved. The OLED display is nice and has some functional merit, but is by no means essential. All in all though, we have here a lens which is extremely satisfactory in use and does the job very efficiently.

Quote:If my Nikon 24-70mm f2.8 G AF-S ED Lens is worth being replaced by the new Nikon Z 24-70mm f2.8 S Lens. A comparison using the FTZ adapter on the Z7. would,I feel, be of great interest to many Nikon users.
While I agree, this is a matter for the ephotozine team
They have tested the AFS VR version https://www.ephotozine.com/article/nikon-af-s-nikkor-24-70mm-f-2-8e-ed-vr-review-28783
While the old test is on a lower resolving D810 it seems clear the S version on the Z7 is dramatically better in the corners and better overall.
Nikon said the new Z mount would lead to better optics. It seems clear from this test Nikon's promise is fulfilled.
Is it worth the upgrade?
Only you can decide if it is worthwhile for you.
I would prefer to wait for a pro grade Z body, very probably in time for next years Olympics to be held in Japan

Well, that comes down to whether you can afford it or not. If you buy a Z7 and put the old F mount 24-70 f2.8G + the FTZ adapter on it, it will be a very large combo and negate any real benefit of the smaller body - if that is what you are after. Whilst I wouldn't call the new 24-70 f2.8S small, it is still much smaller and lighter than the old 24-70 f2.8G especially when you factor in the FTZ mount if you want to put it on a Z6/Z7. I own the 24-70 f2.8S and as for sharpness and resolution well, the new lens is much sharper, sharper edge to edge, sharper whether close or at distance, has beautiful overall IQ and excellent build quality. Whilst the old 24-70 f2.8G was an excellent lens for it's time, it was only reasonably sharp wide open (never great), but the new 24-70 f2.8S is as sharp side open as it is stopped down. You will be happy to shoot wide open all the time. Overall, this lens gives most primes a run for their money which can't be said of any 24-70 f2.8 type FF mounted DSLR zoom. This is a true pro spec lens and I agree completely with the Ephotozine's verdict - they pretty much always get it right. The 24-70 f2.8S lives on my Z7 now.
Z7 sensor has a resolution of 8256*5504. That is to say the maximum measurable value of sharpness is 8256/2 (=4128) LW/PH. How can you get the sharpness of 4750+ LW/PH, even higher than the theoretical value?

Could you kindly to update the link, please?
The image in the link shows a target separating from the "backing board" in 2 places, and of dubious contrast as the detail in the centre of each slanted Imatest panel is not defined.
There is no explanation as to whether by edge you mean the "top" edge where the most Imatest target detail is at about 10mm from the image centre on 24x36 format, or near "outer" edge at about 16 mm.
The tripod and head has relevance to an amateur on a limited budget but to me seems somewhat below a top quality set up, and especially so when testing longer focal length lens.
As I see it the link currently demonstrates a test procedure raising questions and not giving a fully credible explanation.
The picture of the test target is of course merely for representation purposes and depth of field is limited so it will appear unsharp. It's just demonstrating the general idea.
"Edge" is near the long edge and is consistent with all lenses. With very long lenses there are many challenges and these are addressed appropriately depending on the lens.
Anybody interested in the theory of lens testing can look at the Imatest website, but it is a lot of technical information and much of it is beyond the relatively simple things we need to know for a review. Consistency is a major requirement and it enables us to realistically compare one lens results to another.

Have you made a typo?
The long edge of the frame at its centre is 12 mm from the centre of the image with 24x36 format, whereas the short edge centre is 18mm. The corner is 22mm.
I presume you do not mean to imply you measure "lines" about 10mm from centre (on 24x36) as this can be largely irrelevant to the edge lines near the shorter edge at about 16mm out or lines in the corners at about 20 mm out.
Quote:With very long lenses there are many challenges and these are addressed appropriately depending on the lens.
I agree.
Printing out a "double normal size target" makes getting the camera exactly at 90 degrees to the target with 24x36 format easier with lenses around 14mm and wider.
Filling the camera frame with an Imatest target with a 400mm requires a focus distance much too long to be practicable indoors.
