Hey all, I purchased a M42 to Nikon adapter a while ago so I could use my Carl Zeiss 58mm Biotar. When I attached the mount to one of my bodies I had a terrible time trying to get the adapter off. The mount would not budge. Before I try this on one of my better bodies I want to make sure that I won't have any problems... how do I get this thing off it sticks? The camera that I tested on was a N55. I hope to attach it to an EM and possibly a D*g*t*l D70s.
