[QUOTE="Horoscope Fish, post: 204656, member: 13090"] I've gone from a D40 to a D5100 to a D7100 and yes, there's a difference in image quality IMO, but it's hard to say how much or to attach a dollar amount to what I'm seeing. I wouldn't give up my 7100 but that has as much to do with the feature-set it brings to the table as it does image quality. On related note, I think the IQ difference has more to do with color *depth*, than the number of raw pixels; your D90's color depth is a respectable 22.7 bits but D7100 comes in at 24.2 bits, and that's significant increase and shouldn't be dismissed lightly. Then there are things like dynamic range, ISO noise, focus points and the number of cross-type focus sensors... So yeah, it's not a matter of one BIG thing here, it's a matter of several small things all adding up. As cost-conscious happy medium you might want to consider something like the the D5200 and a really good prime lens if you don't have one already. The 5200 would be a significant step up from the D90, yet considerably less than the D7100. [/QUOTE]
