Thanks Nick, but I'm sure the camera was a goner. Minolta Maxxum 7, bought it brand new many, many moons ago. Always been a Minolta guy since the manual focus days. It was my last and best 35mm camera. The aperture control mechanism inside the lensmount broke. I nearly cried. Because it's electronic (and as Minolta only makes office copiers now) nobody I contacted would even look at repairing my camera. Maybe if it had been another brand, but not mine.
