Product was well packed and not over the top in a large box for the product. The adapter itself is packed in a matching box for its size. However, there is currently no description how the adapter on the lens and lens mount is to be mounted. Even if you figure out the self and also is not difficult, here to deliver a star.
The adapter itself comes without a lot of function. This means friends of autofocus: Here you have to focus manually. Material feels valuable and has no visible scratches. Whether loosen the small screws for the springs and lock after a time, I can not say yet. Since one week but everything is still sitting firmly on the lens and camera.
Installation was easy. Creating Adapter on the lens and rotate until it clicks, then nothing may also wobble. A little power you need already, because the Adapter difficult turns, but is good for strength. Then brought the lens as usual also to the camera.
I have a Carl Zeiss tested 15 mm / F2.8 DISTAGON on a Canon 600D and a 5d and for me held the lens bombproof on both cameras.
Because I want to use from time to time Nikon lenses on my Canon cameras and renounce the autofocus and aperture-adjusting the lens, this adapter is right for me.
