Well written and very interesting. I struggle all the time with getting into FF. I have the 7D and 50D (thinking of selling the 50D to get FF), but quite frankly other that one stop noise improvement, I'm not sure I would like the loss of reach or how quite frankly, the pictures would look any better. I have read extensively on this issue and still can't seem to make the decision to go to FF. I agree the 6D is not the model I would want, I think I would go with the 5DII is I were to get anything in FF. I think Canon has really lagged behind in recent years to Nikon with in regard to the AF situation and sensor development. Even Fuji now has a nice sensor (Xpro1 and XE1) and Sigma with their Foveon sensors. Canon's first attempt at mirrorless has been quite a disappointment too. I may wait for the 7D upgrade (who knows when) or still agonize daily over the 5DII.
