I'm really only posting for tea and sympathy here. :tongue: My GRD IV is doing this: [video=youtube_share;KRSn6uWjpRg]http://youtu.be/KRSn6uWjpRg[/video] I changed the battery. I left the battery out for awhile. I used a bit of compressed air to try and blow any lint or hairs or whatever out. No luck. And there has been a weird smear(?) on a couple of shots recently. You can see it up at the top right hand corner of this shot. I don't know if the issues are related or not. It's very strange. I noticed it in another photo with a lot of sky, but then some others didn't have it. Any ideas? I have packaged it up to send to Pentax Canada today. It is amazing how attached to a camera one can get. I haven't been able to use it for 5 days and I really miss it. It's the first camera I've had that I carry with me almost all the time.
