I've noticed a recurring issue with my OM-D and am wondering what the heck I'm doing wrong. This does not happen with my E-PL5. Every few dozen shots or so I get one that looked great in the viewfinder but ends up very underexposed (like 1.5-2 stops!). I've triple checked my metering mode and exposure compensation, and the underexposed image seems random. To top it off, every once in a while the camera shoots a completely black frame! Many of these shots are outdoors on a sunny day, so lack of light should not be an issue. Anybody have any ideas? I tried another SD card (the one from my PL5), and the same thing happens. The lens I'm using doesn't seem to make a difference either.
