That's a great question for me because I already have a GA645. I really like that camera a lot, but still pine for a GF670, for several reasons. One, I want to shoot naturally in landscape format. The GA645 is normally in portrait mode. I'd like a manual focus lens to shoot with sometimes. And of course the GF670 has a much bigger negative. But maybe I could live happily with the GA645. It seems to make even more sense for me to get a GA645Wi, so that I can have two cameras with different focal lengths. That really would be best, except I want that dang larger negative!!
