Not digital, but still a lens problem - aperture blades are stuck - advice needed
Sorry to discuss a non-digital lens, but I'm hoping someone can advise me. I have a very nice 28mm wide-angle lens from the days when I was shooting 35mm film in my Minolta XG-2. It's an ordinary manual lens, not auto-focus. It's been sitting in my camera bag for ages. The other day, for no particular reason, I took it out to have a look at it and found that the aperture blades were stuck in the wide-open position. Usually you can close them by moving the little spring-loaded lever at the back of the lens, but now all that happens is that the lever moves as usual but not the blades. I've tried gently banging the lens on my palm, but no dice. Has anyone any suggestions how to fix this, short of taking it to a camera repair shop?
