How sharp is the viltrox af 90mm f 2 2 evo?
I don't have sharpness test results for the Viltrox AF 90mm f/2.2 EVO, so I can't give you a verdict on how sharp it is. Here's what the lens page does cover: it's a 90mm prime for APS-C, which frames like 135mm on full frame. At f/2.2 it gives about the depth of field of f/3.3 on APS-C. It has autofocus, no stabilisation, and mounts on Sony E, Fujifilm X and Nikon Z. The full Viltrox AF 90mm f/2.2 EVO page lists every body it fits.
If you plan to shoot portraits, the thin focus zone at wide apertures matters more than lens sharpness in practice. The Portraits guide explains how aperture affects what stays sharp.
