I picked up a pair of lenses for my father's C3 on ebay a year or two ago. Read the directions on removing the lens from the camera body, got it to turn somewhat, then noticed a retaining bar that wouldn't let the lens turn any more. Never did get it off, then set everything aside in disgust. I don't see them handy at the moment, so I can't tell you what they were, other than a wide angle and a tele. One of these days...
