>>4433691>film flatnessMaybe. Some medium format SLRs have better designs for the film plane than others. For example many people use the press backs from the Goose and such on the RB67s as they hold the film flatter than the regular 120 cassettes. Some people also use the 220 backs as they have a stronger pressure plate. I would say the real advantage of MF SLRs over MF TLRs is the obvious: better lenses, only needing one lens, real TTL image viewing. The fact that SLRs replaced TLRs also means that pretty much all of the lenses for SLR are much newer and better than TLR ones, with the exception of fossils like the C330s that managed to hold on until the 90s or 80s or whenever they stopped making that thing.
