I use the lens adapter on my Nikon D60 with an old Schraubobjektiv that has done 3 times at a Praktica MTL his service. The processing of the adapter is very good, it fits both the object and the camera without problems. In addition, no play is detected. A "corrective lens" is also inserted into the adapter. That with this lens adapter aperture and focus automatic camera lapsed should be clear: The adapter is purely mechnisch. So the camera should gleichschalten on the M program and make course focus manually. Unfortunately, I have it still did not manage with my lens to achieve beautiful, clear shots. The lens is a very weak light and simple telephoto lens with 500mm focal length and a smallest aperture 8. The low quality of the lens may be one reason for the disappointing images. I can the adapter facing the other reviews therefore only recommended if the object to be used what is good. The supposed "infinity setting" does not appear to work correctly with the other. I have pictures of the Moon made with tripod and remote release, all of which were heavily blurred, although the moon in the viewfinder looked Ok and the focus was on infinity. I can not exclude that it is an operator error on my part, but warn at this point in this issue.
Conclusion The product is processed properly and allows the connection of old lenses on the bayonet connection of modern cameras. However, whether the images are good what is an entirely different question. Whether one is an experiment worth EUR 25 each must decide for himself. I think the price of the offered (material value, production) exaggerated and only considering the probably very low numbers just fine. Therefore 4 stars.
