Is there a power supply available for the E-PL1, so I can power the camera from the wall and not batteries? Since you can't capture frames via USB, I need to start using my E-PL1 to shoot frames for stop motion animation. Removing the camera from a tripod to constantly change batteries is not an option, so I was hoping to find a power adapter. The Olympus site is unclear whether their AC-1 adapter will work with the E-PL1. It doesn't look like it does.
