Bud,
The D7100 is a Nikon DX frame camera. It has an option in the menu to shot in the standard DX mode or a 1.3 crop mode. In the crop mode it does not use the whole sensor. A 35mm DX lens would record an image equivalent to one taken with a 45.5mm lens when the crop mode is selected. It is a little bit of a gimmick as the same thing can be accomplished in post processing.

Thanks for the info.
