Review VerdictThe Viltrox AF 50mm f/1.4 FE Pro is an impressive lens in many ways, but it's not flawless. In terms of sharpness, it is up there with the best, though. Image distortions and lateral CAs are low. The vignetting is about typical for such a lens. The quality of the bokeh is generally good with a few caveats. Not ideal are axial CAs at large apertures as well as the observed focus shift at close focus distances. Unfortunately, Viltrox does not provide a built-in correction profile, so let's hope that it'll be made available via RAW converters or via a future firmware update. In terms of build quality, we have (almost) nothing but praise. The lens feels like a tank - but it is also about as heavy. The handling of the control rings is superb. Unlike in their budget lenses, the AF 50mm f/1.4 FE Pro is also weather-sealed and the upgraded AF motor is surprisingly fast. It also undercuts the price of the (serious) competition by quite a margin. So unless you want to invest an arm and a leg, the Viltrox AF 50mm f/1.4 FE Pro should be on your radar.

Where can this lens be adapted?

The Sony E mount has a flange distance of 18 mm. A plain adapter fits a camera whose flange distance is at least 1.46 mm shorter. How lens adapters work

Native lenses set the aperture, and often the focus, electronically. On a plain adapter they do not work. Use an electronic adapter made for this pair; for many pairs nobody makes one. Fully manual lenses are the exception.
