First of all the 33mm lens on APS-C works out to a 49.5mm equivalent, very close to the 50mm perspective on full-frame. This doesn’t make the lens better, but my preference is for slightly wider (I prefer 40-45mm) for my style of photography. However the build quality of this lens feels better than the XF 35mm f/1.4. The Viltrox lens is bigger and heavier, although this allows for a much larger and more natural feeling manual focus ring. The aperture ring on the Viltrox does not have hard stops (except when you turn it to A mode); although the actual diaphragm opening is set to 1/3 stop increments, not a smooth transition between stops like on many cinematic lenses. There is a warning for X-Pro owners, that the Viltrox 33mm f/1.4 can scratch the lens release button due to it’s close proximity to where the lens and mount meet. I have a slight scratch on my X-Pro3’s lens release button, although I don’t know for a certainty if it was because of the Viltrox lens. The lens clearance is good on my X-T4 and even better on my X-H1.
