Canon ef 14mm f 2 8l ii usm vs zeiss milvus 15mm f 2 8?

The main difference is focus. The Canon EF 14mm f/2.8L II USM has autofocus, and the Zeiss Milvus 15mm f/2.8 is manual focus only. Both are f/2.8 primes for full frame, and their focal lengths are close enough that the choice is mostly about how you shoot.

If you want autofocus on a Canon EF body, the Canon is the simple pick. If you shoot Nikon F, or you prefer turning a focus ring yourself, the Zeiss is the one to consider, since it fits both mounts.

For what the crop means on your body, see the sensor sizes guide and the focal length converter.
