My Pentax has been suffering from the dreaded mirror-flop issue, rendering the camera useless on a full battery. This started over a month ago, and has a workaround of only using partially charged batteries. The lens release button fell off at some point on Saturday, so my 18-135mm lens is stuck on the camera. Said lens also has serious auto-focusing issues, only locking focus 50% of the time. It's time to send the whole enchilada to Pentax for repair. Viewfinding finally took it's toll on the poor fella.
