Ray why would the noise performance be better on the D610/D750 versus the D7100 or D700, particularly when using RAW
D7100 = 24MP = DX
D610/D740 = 24MP = FX
bigger pixel density per inch on D7100
I can understand why with jpegs could be better because of the (new) better engine … but with RAW I do not understand why, as any noise reduction should be the same "in camera" (is there any - don't think so) or in specialist software.
same comments with the D700
I crop a lot - use spot, (single cell), focus and spot exposure - generally with bird photography
AF tracking does not concern me too much .. as I am OK with BIF with the D7100 or D700
Pixel density and pixel size are a large part of ISO performance in my experience given similar age technology. It was the same with the D300/D700 as it is with the D7100/D(pick your 24mp FX). The D800 in 15.3mp DX crop also produces cleaner images than a D7100 at the same ISO and the D7100 is a year newer. Since you say you crop a lot the pixel density you will lose with the angle of view difference may be a big consideration.
