Nikon recently released its newest DX camera body called the Nikon D7100. It is the upgrade to the Nikon D7000, but in my opinion, it is a whole new breed of DX bodies. The general size and weight is about the same as the D7000, but it features a new 24 megapixel sensor, compared to the D7000′s 16 megapixel sensor. It has a ton of features that are common on FX bodies, but not seen on DX bodies. Below is a comparison between the Nikon D7100 and D7000 camera bodies.
These are the biggest differences between the two cameras in my opinion. From all of the test shots and reviews I have seen, it looks like one heck of a camera! The Nikon D7000 is a GREAT camera, so if the new D7100 can top it, it is something amazing!
