Fits the camera port, flange back is wrong

The adapter fits properly on the camera port, it can be turned easily and sits firmly on the camera.
However, one should note that this short adapter leads to a shortened flange. The Unendlichstellung on Objektv is so somewhere in the middle of Fokussierumfangs. That does not bother especially if you want to focus on further distances. So thus is hardly possible eg wildlife photography. For more distant objects, such as at the moon photograph but the adapter is suitable because it can provide beyond infinity sharp.
