Please help me understand the severity of this problem... I was using my EPL1 with the Panny 20mm. I decided to try AF-C for the first time (while in my preferred mode - Aperture priority). I snapped about 4 pictures, and then my camera absolutely froze. All the buttons became unresponsive but I still had live-view on the screen. Even the power button was unresponsive, so I could not turn it off... and even after waiting for 30 min, it would not go off by itself. Finally, I pulled out the battery - put it back in again.... and all is now seemingly fine. Was this a common Microsoft-Windows-crash-like moment, or was it indicative of something more serious? Someone had previously experienced something quite similar (as mentioned in a previous thread), with the same configuration (Pen and 20mm). However, the thread did not have a definitive answer and it got sidetracked by issues of autofocus locking up (rather than the entire camera freezing). Any ideas/comments? In anticipation of the question: Yes, both the body and lens are still under warranty.
