Hi, all. I am new to the forum and am hoping you can help me understand the differences in picture quality between the D200 (DX) and the D700 (FX). Although the D700 is a full-frame camera, the RAW file sizes it produces are substantially smaller than those created by the D200 (10MB vs. 16MB). There is a similar difference in JPEG file sizes. This is such a basic question, I am embarrassed to ask, but why is that? To me, the smaller file size implies lower resolution, more noise, less enlarge-ability. That's probably wrong-headed, but can someone explain how the D700 is an improvement over the D200's images? Many thanks!
