I'm looking to buy a single camera to use both as a personal snapshot camera and as a video camera to document my artistic work (mainly kinetic sculptures and light installations). The micro four thirds format is appealing for its compactness, as well as the short flange focal distance which allows potentially broad lens compatibility.
I was all set on buying the Lumix G3 but then I discovered it has no manual controls for video. I want at least aperture priority as the Vimeo shallow depth of field eye candy effect is kind of important in my field... The Lumix GH2 has manual video controls but it's simply too big to be called 'compact'. The Olympus PEN cameras have manual video controls, but seem to get bad reviews for video quality.
What's a good EVIL/CSC alternative? Ideally no bigger than the Lumix G3 but with the video controls and quality of the Lumix GH2. Could I adapt+attach a lens with a manual aperture ring to the G3 (to escape the no-manual-controls problem) and trust the G3's auto ISO + shutter speed to give me acceptable results?
