Daniel - hard to make a comment because obviously it largely depends on your style of photography. I think a film BU to the M9 does make a lot of sense, and like others here, would imagine something like an M6 TTL would actually be better as that that BU rather than an MP. I think the FM3a is one of the best cameras EVER but then I wonder if it's just duplication in many ways to the RFers... perhaps keep the F6 and buy something like an AF 70-210? Sell the rest (gulp!) Then you'd really have everything covered? Just a thought.
