Irony must be the flavour of this thread: we have so much angst, anger and pontification, but there seem to be two people available to LuLa who could make relevant comment, and neither chooses so to do.
The surprising thing, the irony referred to above apart, is that anyone not already a pro with the work type required to justify that sort of expenditure, would choose to be in the MFD system - of any brand. Yes, it would make me wince, but I could go out and write the non-bouncing cheque, but as a guy who did also own and sometimes need film MF, my life as a retired photographer would not be one iota the better for that purchase, now, as an amateur. I'd rather help feed the starving or give money to a hospital charity than blow it on an ego trip like that. Insofar as the photography goes, format doesn't give you talent; Leica doesn't give you talent, my Rollei TLR didn't, Nikon didn't and neither did Hasselblad. (I can't speak for Canon - never been there.) They are all just tools - some more suited to some jobs than others. Anyone buying into MFD thinking it'll make them better photographers is insane. It may allow them to produce the same old same old, just bigger.
