I have a GW690II, I've owned the GS645S and I've handled the GA645. Forget the fact that they all share the same brand name and take 120 roll film - in practically every other way, the GF670 is an entirely different animal. In optical character, feel, handling, construction, features - a whole different ballgame. It's easy for me to imagine a user liking the GF670 and not the others, or vice versa.
