24.1-megapixel DX-format image sensor, superior low-light performance, ultra-precise autofocus and metering, advanced video recording features, built-in HDR, mobile connectivity and much, much more. Pair it with any of Nikon's superb NIKKOR DX- and FX-format lenses, versatile Speedlights and accessories, and the D7100 will be the centerpiece of your creativity for years to come. The D7100 marks an exciting advancement in image quality for high-resolution DX-format cameras. Nikon specially designed its 24.1-megapixel DX-format CMOS sensor without using an optical low pass filter (OLPF), resulting in the purest, sharpest images using D7100's DX-format CMOS sensor. Combine that with fantastic ISO performance at both ends of the spectrum—down to ISO 100 and up to ISO 6400—the processing speed and intelligence of EXPEED 3 and the extra lens reach of a 1.3x crop factor, and the D7100 is the ultimate tool for those seeking a lightweight DX-format HD-SLR.
