Is the viltrox af 35mm f 1 8 evo worth it?
The Viltrox AF 35mm f/1.8 EVO is a good pick if you want a wide-ish prime for people, groups and environmental portraits. It's autofocus, f/1.8 and full frame, and it fits Sony E and Nikon Z. It has no stabilisation, so it leans on light and fast shutter speeds. Its lens page lists every body it fits.
I'd pair it with a full-frame body, such as the Sony a7 III or the Nikon Z6 II. On APS-C, such as the Sony a6400, it frames like a 52mm, which is more of a standard lens than a wide one. If that's what you want, it works, but it isn't the same lens. For more on whether full frame is worth the extra weight, see sensor sizes, and for portrait lens choices, see portraits.
