I think people seem to feel that full frame is a BETTER and SUPERIOR format. It isn't. It's just different.
APS-C 1.6 crop is smaller. But it's just as VALID of a format as full frame. It's just different.
Each have their own sets of advantages and drawbacks. But I'd NEVER EVER say one is superior to the other. Both are well within the range of delivering very high quality professional-grade imagery.
I think people just gotta stop thinking of FF as superior and just remember that 1.6 crop is just as valid of a format as 35mm. Remember, at one point 35mm was considered to be the crappy format for soccer moms and the clueless public.
Different, not superior.
