Cheap aperture electronics more unfortunately not

Already at unpacking, I realized that the cable, which both adapters twists is very stiff, which then turned out to be as a major shortcoming. Leading the way, the only positive to the adapter was 100% functioning electrical connection, if there was not the problem that the camera-side ring does not read lock, but you could turn at any time. Combined with the rigid cable of course the risk was to adjust the autofocus while always unsuccessful attempt given that the ring rotates along and bang the electrical connection was interrupted. Neither aperture autofocus still went back.

Manual focus could then mostly forgotten, because the cable regularly led to adjustments here.

The remaining processing was not satisfactory. So the lens side EF mount was rather hakelig, it creaked every time when releasing and locking the lens and in addition, this required quite a bit of effort. All in all, I am not convinced of the adapter. I will but on a standard Retroadapter without electronics, but with full aperture - which anyway is the only option in retrospect, change.

Conclusion: The adapter agrees only to adjust the aperture, the rest is manual fine work.
