Just wondering how many of you use an external flash on your G9/G10/G11 body, and if you do - which one? I'm a Nikon DSLR shooter, but like the G11 for a compact setup. I was looking for a flash similar to the Nikon SB400 (bounce capable) but having trouble finding anything small like that with bounce ability. Edit: I guess it would be the 270EX? Thanks!
