I just got my camera back from pentax a month or so ago, I sent it in for them to fix the mirror flop issues I'd been having. Originally, I would only get the floppy mirror when using live view, but now it's started doing it even with live view off.
Here's a video I took last night. (sorry about the terrible quality)
Pentax K r Mirror Flop - YouTube
I've not really noticed many problems with my modern lenses, but every time I try to use my M 50mm f/1.4 it takes one or two normal shots, and then starts flopping around like a fish out of water, eventually getting stuck, and requiring me to remove the battery in order to unstick it. Unfortunately, it's even worse now than it was before I sent it in.
I've heard that cleaning the lens contacts can help, but the M series lens doesn't have any. My battery wasn't fully charged at the time, which I've also heard can cause mirror flop. (I've got a AA battery holder on the way, so we'll see if that fixes it. It's a bit of a pain to have to buy the adapter and use only AA's if I'm going to be shooting with my older lenses if it does, though.)
For those of you that have had mirror flop issues, does this look the same as what happened to you, and how did you fix it, if not by the methods mentioned above? Also, has anyone had theirs 'repaired' by Pentax, only to have it start acting up again, or did mine just slip through the proverbial cracks? I'm debating the merits of sending it in again if they have a poor track record of fixing it and using AA's works.
