I'm not able to use my camera. I have an 'Error Press shutter release button again' message but when I do nothing happens.When I removed my lens and looked inside as I pressed the shutter I could see only one side of the shutter was lifting. I've only had it 2 and1/2 yrs. I wonder how common a problem it is as I talked to someone recently who had same message (his was only 1 yr old and out of warranty)and when they sent it away to Nikon the reply was that moisture had got in and corroded it. I don't want to have to spend money to get the same answer so think I might upgrade and buy a new body. This is my first Nikon SLR I've always bought Olympus so disappointed.
Welcome to Nikonians! Sorry to hear about the problem with your D3100. Unfortunately anything electronic or mechanical can fail at any time, regardless of brand. I would send the camera to Nikon Service or a Nikon Authorized Service Station and get an estimate (free). Then you will be able to make an informed decision. It is usually much cheaper to have the camera repaired than replacing it.
Thanks for your reply. You're probably right and good to know I can get a free estimate. I have enjoyed the camera and it's a good size for travelling with. I still think it's a too much of a coincidence that this model seems to have had shutter problems from the start.
I've never heard anything about the D3100 having any sort of widespread shutter issues. Your friend's issue from moisture and yours are probably completely different. The error message you got shows up for a variety of issues, not just the shutter.
I've had it repaired and I'm due to collect it. The repairer thinks I must have knocked it. That's the trouble with plastic bodies I guess. The repair was cheaper than buying a new body and ut's fully serviced so hopefully it will go on for a few more photographic expeditions. Thanks for your help
