I had dusted off the old placements my father recently and a couple of Zeiss lenses found in the 70. Since I wanted to know how the work on my A77, I bought this M42-on-A-mount adapter. This works great! The adapter is stuck, does not wobble and is very thin. AF does not work of course, but the recent A-mount cameras help with focus highlighting and -Peaking super when manually zooming. Since M42 must be screwed tedious and the adapter costs only 10, I wonder if I should not buy me one for each lens easily.
The old Zeiss lenses function the way really good on the A77 and are modern lenses in terms of sharpness, contrast and distortion in anything close - on the contrary.
