How much better is D7 100 than D7000?

Low-pass and 24 million pixels bring high resolution, but it is only helpful for industries that need large-format and high-precision output, such as landscape photography or commercial photography. For ordinary photographers, it is more of a burden, with larger original file size and slower post-processing speed. Except for the resolution, the two components are almost the same in color depth and sensitivity range. If you don't pursue ultra-high resolution, these two bodies can be said to have almost the same picture quality.
