the adapter is very high quality. Full Metal in very solid copy. The adapter is flush with the NEX and has no play. It wobbles nothing. The aperture ring engaged in all positions exactly one with the feeling of being something hakelig, I think, however, that adjusts with increasing use here with the time some wear and smoother. The lever for the aperture setting can if necessary be set if this would scrape too close to the lens mount of the lens .. Mounting the lens on the adapter goes sometimes too strict, both are extakt on. Man but is afraid that no no longer the lens can be solved by the adapter. It takes some force when turning. The Bajonettentriegelung could go easier. Here also the feeling when one pushes too much that it is bent .. Otherwise, all Sony / Minolta AF lenses can be connected. However, no AF and the camera has to be operated in A mode. In addition to triggering the camera without a lens must be set.
