Viltrox AF 28mm f/1.8 Z Review
Viltrox AF 28mm f/1.8 Z Full-Frame Autofocus Lens for Nikon Z-Mount
I have reviewed several Viltrox lenses for my Fujifilm X Series cameras and have especially been impressed with the Viltrox AF 13mm f/1.4 XF and Viltrox AF 56mm f/1.4 XF so far.
The Viltrox AF 28mm f/1.8 Z will be the first full-frame lens that I have reviewed from Viltrox and I paired it up with the new Nikon Z8 for a weekend of street photography and general travel photography.
While maintaining a compact size and moderate weight for such a wide aperture lens, I was excited to see how the Viltrox AF 28mm f/1.8 Z would fare on a full-frame camera.
Introduction
The Viltrox AF 28mm f/1.8 Z was released in late August 2023 and is Viltrox’s latest lens. It joins a list of several f/1.8 prime lenses, 20mm, 24mm, 35mm, 50mm, and 85mm. These lenses share a max. f/1.8 f-stop and this is intriguing as it seems to strike a good balance between size, weight, price, and performance.
For full disclosure: Viltrox sent me the AF 28mm f/1.8 Z lens for my review and I get to keep it after the review. Vitrox, however, has not dictated a narrative in any way, and the opinions in this review are my own.
At the time this review was posted the Viltrox AF 28mm f/1.8 Z was listed at $379.00.
Viltrox AF 28mm f/1.8 Z - Handling and Specs
Speaking of size and weight first, the AF 28mm f/1.8 Z balances perfectly on the Nikon Z8 and does not feel heavy. It would be an equally good match for either a Z5, Z6, Z7, or the new Nikon Zf without getting too big.
At 12.9 oz, 367 g, the weight is almost squarely in between the 56mm f/1.4 XF and 13mm f/1.4 XF I mentioned above, and it is nice to learn and feel that the weight didn’t have to increase considering we are now using a full-frame lens.
The overall build quality feels solid with a nice metal mount and smooth aperture ring. The aperture ring, however, is not clickable but instead adjustable in variable f-stops which should make video shooters happy. As a still shooter I would have preferred clicked stops.
On the Nikon Z8, I often chose to put the lens in the A position and then used the command dial on the camera to adjust the aperture. This way I found that I had accurate control.
The lens does not “click” into the A position as with most lenses. Instead, the resistance of the aperture ring gets harder towards the full A stop. I have never seen this before but it is cleverly done. There is no AF On/Off switch on the lens.
The included plastic hood is a bit disappointing. The hood clicks into place just fine but feels a bit flimsy. The Viltrox lenses I have reviewed previously came with a wonderful metal lens hood which instilled a satisfying sense that you are handling a quality product.
The STM autofocus motor is fast and accurate, and I didn’t hear it. I can confirm that it is compatible with Nikon's eye-detection autofocus mode.
The optical formula mentions three ED elements, HD nano multi-layer coating, and a 9-blade diaphragm. The filter size is 55mm and the minimum focusing distance is 14.6", 37 cm. You can update the lens firmware via a USB-C port.
In Action
I have been flirting with the 28mm focal length for quite some time now. Especially the Leica Q, any of the models, have been tempting but I always worry that it is a fixed focal length camera only.
On my Fujifilm X cameras, the XF 18mm f/1.4 R LM WR has been very good but at times, if you are after the full-frame look, you have to go full-frame and it usually means a jump in price and weight.
Things are, however changing, and swinging this lightweight AF 28mm f/1.8 Z option was effortless. I was testing the Nikkor Z 85mm f/1.2 S at the same time and while this is a great lens, I much preferred walking around with the smaller and lighter 28mm lens.
Please do not see this as a strike against the Nikon 85mm lens. Personally, I was merely gravitating towards the more compact option when having the choice for a photo walk. The 85mm would mostly certainly shine in other scenarios.
Viltrox AF 28mm f/1.8 Z - Image Quality
Sharpness is good in the center at f/1.8, while the corners are slightly soft. Corners, however, are not distractingly soft and images sharpen up nicely as you stop the lens down. I would not be afraid to use the Viltrox AF 28mm f/1.8 Z wide open.
Bokeh, while perhaps not over-the-moon wonderful, is smooth enough and has a nice transition from foreground to background.
Color rendering on the Nikon Z8 was pleasing to my eye with the Viltrox AF 28mm f/1.8 Z and I did not find it radically or distractingly different from the images I shot with the Nikkor Z 85mm f/1.2 S at the same time.
I am sure if you put the images under a loop or pixel-peeped, you would find differences but viewing images full screen the two lenses worked well together as a pair. I will have a first impression look at the Nikon Z8 coming up with images from the 85mm lens as well.

Conclusion
If you favor native lenses, Nikon has a couple of similarly priced compact options. The Nikkor Z 26mm f/2.8 is priced a bit higher at $496.95, and the Nikkor Z 28mm f/2.8 is a tad lower at $296.95. I have not reviewed these so unfortunately cannot comment on image quality.
I predict that both Nikon lenses would be fine but they are 1 1/3 stop slower than the AF Viltrox 28mm f/1.8 Z. This will affect your ability to shoot with a shallow depth of field, and the Viltrox lens will excel in this regard. Both Nikkor lenses are, however, more compact and under half or about a third of the weight of the Viltrox lens.
If you are looking for an f/1.8 lens and can live with the 35mm focal length instead, Nikon has an excellent Z 35mm f/1.8 option but at the cost of $846.95, you would be looking at spending more than double the cost of the Viltrox 28mm f/1.8.
The Viltrox AF 28mm f/1.8 Z surprised me mostly in good ways. It offers a compact, lightweight, and yet fast full-frame option at an affordable price point, and it delivers very decent image quality.
The overall build quality is perhaps not quite as nice as on the Viltrox AF 13mm f/1.4 XF (Pro Badge) that I reviewed last year and the omission of the metal hood is unfortunate but of course not crucial for the final image quality outcome.
While the Viltrox AF 28mm f/1.8 Z may not deliver results like a Leica Summilux 28mm f/1.7 or Sony FE 35mm f/1.4 GM it still delivers impressive results at its price point and offers a good value proposition for the Nikon Z-Mount.
Pros
An affordable wide-angle option for Nikon Z-Mount
Fast f/1.8 max. f-stop
Overall decent image quality
Internal focusing

The omission of a metal lens hood as seen on other Viltrox lenses
