Picking a 50mm lens for your Nikon Z system just got more complicated. The Viltrox 55mm f/1.8 from the Evo series is an apochromatic lens priced at $370, and it's gunning directly for the Nikkor Z 50mm f/1.8 S.
Coming to you from Dustin Abbott, this exhaustive head-to-head video breaks the comparison into four categories: build and features, autofocus, video performance, and optical performance. Abbott shoots both lenses on a Nikon Z8 and works through dozens of real-world and controlled tests to find a winner. The Viltrox jumps out to an early lead on price alone, a $300 gap at MSRP is hard to ignore, and it compounds that advantage with a smaller body, lighter weight, a physical aperture ring with click/declick options, a function button, an AF/MF switch, and a USB-C port for firmware updates. The Nikkor, by contrast, has an AF/MF switch and not much else in terms of physical controls.
The autofocus category closes the gap. Abbott notes that while both lenses use stepping motors and focus quietly and accurately, the Nikkor edges ahead in raw speed and benefits from first-party algorithm support on Nikon bodies. That means no waiting on third-party firmware updates when Nikon pushes a camera update. In video, the Nikkor pulls further ahead: Abbott finds the Viltrox occasionally lags before starting a focus transition, while the Nikkor responds immediately every time. The Nikkor also shows less focus breathing and, on bodies with focus breathing compensation, gets the benefit of that correction while the Viltrox does not.
Then comes the optical performance, and this is where the comparison gets genuinely difficult. Both lenses show heavy vignetting wide open, though the Nikkor is slightly better there. The Viltrox has virtually no distortion; the Nikkor needs a small correction. Sharpness splits interestingly: the Nikkor has a marginal edge in the center, they're equal in the mid-frame, and the Viltrox clearly wins the corners. Chromatic aberration control is outstanding on both, to the point where Abbott couldn't get either lens to fringe on guitar strings, water droplets, or shiny oven knobs. Color rendering is essentially identical. On bokeh, the Viltrox produces slightly softer, smoother out-of-focus rendering due to its longer focal length, but the Nikkor delivers cleaner bokeh quality near the corners of the frame. After tallying every category, the final score is eight points each.
Abbott's conclusion is that if you want the better value proposition outright, the Viltrox wins on size, price, and features while matching the Nikkor optically. But the Nikkor has been on the market long enough to appear used at prices competitive with the Viltrox's MSRP, and it carries the reliability and support network that comes with a first-party lens. Abbott calls it one of the best, if not the best, 50mm f/1.8 lens he's ever tested across any platform. How he breaks down the final buying decision, and which specific optical results pushed the score to a tie, is worth seeing in full. Check out the video above for the full rundown from Abbott.
