Can’t replace the battery on the GH2 when a Manfrotto tripod mounting plate is attached. Boo. Surprised that they missed this. -1, Panasonic.
UPDATE: A chap on mu-43.com correctly noted that I can rotate the mount 90 degrees and gain access to the battery. That works, although you do have to take the camera off the tripod before changing batteries. Now, where do I get spare batteries!?
