I juts picked up a EOS M from vistek. One thing I immediately tried was attaching a manual Zeiss Lens with the adapter.
It mounts without issue, accounts for the correct exposure reading but does not allow a picture to be taken. Also the record button in Video mode does not work with a manual lens.
Any ideas, is it disabled ?
(Ps, the cam's AF is fine, its just the lens's that are *%&# slow, attaching 24-70 and 70-200 to it, the M is competitively in line with full Canon DSLR's )
