I really couldn't be happier. The camera recognizes the ADATA 64GB SDXC Card, the Bower batteries and charger seem to work and hold more charge than the battery that came with the camera, the Wooden Camera Hot Shoe and the Kamerar hot shoe extension made it easy to mount the mic, top handle and recorder, and the iris and autofocus on the Oly 11-22 seem to recognize commands from the camera. The only thing that doesn't work is the trigger on my pistol grip, which works fine on Panasonic cameras, but is clearly not real LANC.
After doing a little research, I have decided to get a Photography & Cinema pistol grip (without a trigger) and a Pro-Lanc LRC-01.
When I get the step-up ring for the ND filter, we'll get out and shoot some side-by-sides with the GH3!
