Used PRO LAOWA LENS 12MM F/2.8 ZERO-D - CANON RF

The Venus Laowa 12mm f/2.8 Zero-D is a compact and bright wide angle with an extreme field of view and three fairly unique features: it is almost distortion-free (“Zero-Distortion”), you can use filters on it, and a shift adapter is available with which you can use it as a 17mm f/4 shift lens on a Sony A7 or A9. With the adapter, you thus actually have two lenses in one.
