Originally posted by stormtech If I remember correctly from your Sigma lens problems, aren't you within driving distance to CRIS?

You must be thinking of someone else, because I'm out in rural Montana.
Originally posted by rawr Indeed. A lot of things can go wrong with a camera (dropped, stolen, battery problems etc). For important events you really need a backup.
Exactly, I bought a D700 as a second camera, but it doesn't use my pentax lenses...
Originally posted by glennbp My 2c; OEM or not, batteries can and do create all sorts of problems. It is amazing how many issues can be resolved by simply purchasing a couple of new batteries. That is ALWAYS the first route to take. Based on what has been said here, it is possible that the mirror mechanism got a little dirt in the wrong place and is intermittently sticking. If you are capable of cleaning this mechanism yourself, I would try that, but be careful as it is delicate. Otherwise, take it to a trusted service center for cleaning and/or repair.
One other thing - if you have that wedding to shoot, you can always rent camera/lenses for a very nominal amount especially for just a couple days.
Best of luck-
You're right, and I just got new batteries in the mail yesterday—tried them and they didn't fix the problem.
