My XZ seized up this afternoon. I went down to the beach after lunching, and tried to get some shots of some really weird clouds (they were brown instead of grey or white) and the camera just refused to work. I thought it was the battery, but it didn't actually close the lens. it just...stopped. The one shot I thought I did get, I didn't. I had to remove the battery from the body and then I put it back in and I was able to shut it down (so the lens would retract). It seems to be fine right now but I think I am going to give it a good run over the next couple of days and if it does it again, back to the reseller it goes! Also, the lens seems noisier on opening and closing than it used to. Any other XZ owners experiencing anything like this at all?
