Introduction
Viltrox offers some of the best value AF lenses on the market and now they have come up with this AF 40mm f/2.5 at $158. It should be one of the least expensive fullframe AF lenses with Nikon Z mount and therefore quite interesting. 40mm is one of my favorite focal lengths. Closer to the human’s natural angle of view than a 50mm, and slightly wider than 50mm, it allows for more context to be included in the image. I prefer this focal length to a 50mm for street and everyday photography. The Viltrox Z 40/2.5 with its compact format is therefore an interesting lens. It is not a Viltrox “Pro” or “LAB” lens, which are their premium series, but very compelling nonetheless. Let’s have a look at it!
I tested this lens on a Nikon Z 7II with its 46 Mp sensor.
