Ok, I've searched, Googled, twisted, and shaken . . . and still can't remove a lens from my wife's trusty FA. The lens is a Vivitar Series 1 90mm 2.5 Macro. The camera body was working fine just prior, and I had removed/replaced the lens several times the same day with no problems. As I was trying to remove the lens, it rotated partially (about 3/4") and then became locked in that position. The posts I've seen regarding this aren't helping. Anyone have a special technique for this, or, a shop I can send it to that will be willing to tackle this? Thanks so much in advance for any replies.
