OK, i will check with the guy, for me if i can't get 50 then i will start with 39 anyway, still it was my dream before that 50 is coming out, and the salesman told me that i can use 39mp now, and when i have more money the difference between 39 and 50 then i can replace my 39 with 50 without buying 50 again full cash, and in this way i can stay upgrading in less spending than keeping bodies and pay again full for new body, but i hope i hope i can earn more these days coming, so then i can go with 50 instead of 39mp, i can't wait to use it [any] and learn with it fast so i will start higher level in my area when i can, just i didn't start any business in photography as many there out using Medium formats and many agencies or companies here wants those over DSLRs owners, it is really ridiculous so fine, i will get a MF and see what they will say then.
how is the market for the digital backs? you could get the 39 now, sell it later and get the 50.. because 50... is 50... that would be insane resolution and detail. DROOOOOL
