I am 100% correct. It's not a sharp. Period. As for those films you mentioned shot on 16mm film with very nice budgets and a full 100 man + crew - yes, there are exceptions to every rule.
LOL, you obviously haven't read the actual tests being done (click the link above). Resolution with the same lens on the adapted NEX is measurably higher than a 5DmkII in the center and averaged over the entire lens, only dipping slightly in the corners. Right there, sharper than still the best value in full-frame motion picture shooting, so good still that Canon had to take it off the market to make their newer, more expensive cameras more attractive to Canon buyers.
Also, you haven't read how Slumdog Millionaire was shot with those cameras either.
Please, continue to punt though.
