In on the Panasonic G3 deal

But I'd like to lock the focus independently of the shutter button as well. I'd like to be able to take an exposure reading from one part of a scene, lock it in, autofocus on the part of the scene I'm interested in, lock it in and trip the shutter without changing either exposure or autofocus. My Nikon D7000 has two buttons you can program to do either function- unfortunately it appears that the AF/AEL function can't be separated onto both function buttons on the G3 that I can see- you either get AF, AEL or AF/AEL on both buttons if you change the function buttons to be the AEL button.

It's confusing, I know.
