Have after much deliberation, despite the two not so good reviews for me to buy this product and have to say that he arrived completely intact with me. He was both perfectly packaged and tightly screwed. The Minolta lenses are stopped by said screw from overspeeding, with the snap lock pin the lens is determined also. On the other side of the adapter is seated properly in my A-mount camera Sony (Alpha 77) which detects the lens on the adapter as such. Due to the fact that I'm not quite trust the tiny screw in the long run I reorder some adapters so as not to have to change continuously well in the near future.
This adapter is provided that I have read and understood only for macro lenses, if you want to dock other lenses that use the infinity setting (Focus infinity) in continuous operation you need a adapter with corrective lens.
