I hear about the great Zeiss lenses, and read the great reviews on them.
My question is, why do they ONLY seem to do manual focus lenses? Could they not really clean up on the high end market by making them work with the Canon/Nikon AF systems???
Thanks in advance,
Here is the real reason why Zeiss does not make AF-Lenses for Canon and Nikon:
From the Zeiss Q&A:
Because of the patent situation, it is not currently possible to offer a ZEISS AF lens for the other camera systems with EF and F mounts
In its collaboration with Canon and Nikon, ZEISS currently is not even licensed to use the autofocus interface on the camera.
As I read in other places, it is not possible for a company outside of Japan to build AF-Lenses for Nikon and Canon cameras, due to patent rights.
