I've read about this problem for years, and yesterday, while pulling out my gear to start shooting a DH race, I noticed the control knob on my Canon A2 kinda 'crunch' instead of 'click' and it didn't stay on any one setting unless I didn't tap it or jolt it. It feels like a spring has popped out of place and is getting all wound up wrong inside there. My camera's something like 4 years old maybe. Is there a chance I can get it fixed without charge? I kinda doubt it, but I've heard about this issue being widespread so I was wondering. I wonder how much EOS 3's are going for nowadays :/
