Originally posted by PALADIN85020 I posted elsewhere, but same thing happened to me. Manual mode. 2-second delay. 18-135mm WR lens. Autofocus. Shake compensation off. No AA filter. Fresh Pentax battery. Triggered the shutter, and it went machine-gun on me. Turned it off; it finally stopped. It took no pictures, but when looking through the viewfinder, the image was very cloudy and spotted. The more I think about it, the more it makes sense that it was the mirror flopping up and down rapidly, since no picture was taken. I've not been able to replicate it. New firmware, anyone?

This happened to me for the first time this morning and it actually did it a few times. It does seem like the mirror is rapidly flopping up and down. My battery was low (genuine Pentax battery) and I had my grip attached (genuine grip) with some rechargeable AA batteries in it. I quickly turned it off both times then back on again and it seemed fine. Any ideas why this is happening? Should I be thinking about sending my camera back? Or just wait for updated firmware?
Also on a separate note - I have a question about the K-3 battery grip (D-BG5), how do I know that it's definitely providing additional battery power to the body? The reason I ask is that when attaching the grip to my body and turning it on the LCD doesn't seem to update to show me the additional battery power. E.g. if my battery three quarters full then I put the grip on I would expect the camera to show the battery charge as full - is that how it works? Btw I am using AA batteries with the AA holder in the grip and not a lithium battery.
Cheers
