It's a confusing listing. The picture shows an adapter with the spring and a removal tool. The instructions for mounting say "turn the adapter till the fixative click". Then the removal instructions say "Remove both lens / adapter together from the camera, press the lens lock and then remove the adapter from the lens simultaneously." This is not possible with this type of adapter...they must have just copy/pasted the instructions from a different adapter.
