I've been using my A75 for about a year now, and it's always performed great. Just yesterday, I was taking pictures with some friends, and put the camera away. Later on, I took it out of the bag, and I was ready to take more pictures, and I found that the shutter release button was stuck halfway. I can still take pictures, but I can't browse them since none of the other buttons work with the shutter button half-depressed. I read that someone else here has a similar problem on a Canon, but I didn't find a solution.
I think I'm still covered by the warranty, but I need proof of purchase to have it repaired. Screwed?
