Fujifilm xf 35mm f 1 4 r vs viltrox af 33mm f 1 4?
Both are fast APS-C primes at f/1.4 with autofocus and no stabilisation, and they frame almost the same. The Fujifilm XF 35mm f/1.4 R frames like about 52mm on full frame, and the Viltrox AF 33mm f/1.4 like about 50mm. The real difference is mounts. The Fujifilm only fits Fujifilm X bodies. The Viltrox also fits Sony E and Nikon Z, so it's the better pick if you might switch systems or already shoot one of those.
If you're on Fujifilm X, the Fujifilm XF 35mm f/1.4 R is the native choice. For a Sony or Nikon body, the Viltrox AF 33mm f/1.4 is the one to look at. For people and low light, both sit in the spot the lenses guide recommends for a fast standard prime.
