The Viltrox AF 56 mm f/1.7 Air performs as well as its brothers with shorter focal lengths and represents similarly high level. Once again we noticed an attempt to break the resolution record and make it on the podium; it wasn't successful but impressive anyway, along with very good performance in the most of other testing categories.

When it comes to the flaws, with such dimensions of the lens and its aperture fastness, some of them were inevitable, like vignetting. We trust that this lens attached to newer bodies, or controlled by a newer version of software, will perform better. In fact the weak performance against bright light was the only thing that surprised us in a negative way. I admit with such an angle of view we expected better results in this categories; anyway other Viltrox devices managed to perform distinctly better.

The problem with a weaker performance against bright light prevailed; it was the main reason why the Viltrox AF 56 mm f/1.7 didn't get our 'Editor's Choice' badge but I admit it was really close. For a turn we don't have any doubts that this lens deserves our 'Good Buy' award – with such a sensational price/quality and price/performance ratios it would be a crime not to distinguish it in such a way. A round of applause!
