Viltrox af 50mm f 1 4 pro vs sony fe 50mm f 1 4 gm?

Both are 50mm f/1.4 autofocus primes for full frame, and on paper they're close. Each gives a natural, slightly tight view on full frame and frames like a 75mm lens on APS-C. Neither has stabilisation.

The main difference in this material is mounts. The Sony FE 50mm f/1.4 GM fits Sony E bodies only. The Viltrox AF 50mm f/1.4 Pro fits Sony E and Nikon Z, so it's the easier choice if you shoot or might switch to Nikon Z.

I don't cover image quality or price here, so compare those before you buy. If you're still deciding on a first 50mm, the portraits guide explains how the focal length suits people.
