hi everyone! i know it's a personal decision, but want some input, am upgrading from a D90, which i've loved, but i want more pro editorial quality and resolution, and i'd like to fine tune my large format art prints for gallery use. ideally, to clear and crisp 24x26 at 300 dpi. i shoot a lot of landscape and i shoot a lot at night and i'd like to make spectacular prints but can't afford to go to the D800's. should i be going to FX if i want to go up a big notch in my output or can i stay in DX and not sacrifice detail on blow up? i have the AF-S 50 mm f1.4 and the kit lens with the D90, so either way i think i'd get a new lens..i'm concerned about the lack of autofocus features on the D610 otherwise, it'd be a shoe-in, but for the extra money to not have that is a major problem, especially when the D7100 seems so strong and has amazing autofocus leeway. would love any thoughts!
