D-Movie for recording and editing full-HD movies and AF-F focus mode for movie recording
The D3100 is equipped with the D-Movie function that enables recording of high-definition movies (with monaural sound) by simply pressing the movie-record button. Movies can be recorded with the same aperture and other settings applied in Guide mode. In addition, the camera also offers an AF-F focus mode for movie recording. When AF-F mode is enabled, the camera focuses continuously during movie recording removing the need for holding the shutter-release button down halfway. The D3100 also offers in-camera movie editing functions that allow users to save a single frame as a still image or delete unnecessary portions from the beginning or end of movie files.
New DX-format 14.2-megapixel CMOS image sensor

The new sensor enables the D3100 to produce high-resolution images with outstanding enlargement capability. The camera makes the most of its normal ISO sensitivity up to 3200. For added shooting versatility, the camera’s Hi 2 setting increases sensitivity to ISO 12800.
EXPEED 2, Nikon’s updated image-processing system
The D3100 is equipped with Nikon’s exclusive EXPEED 2 image processing system. The leading-edge technology of the original EXPEED system has been refined, maximising the camera’s power to process the large amounts of data generated by the D3100’s 14.2-megapixel CMOS sensor. EXPEED 2 meets the demands of the D3100’s advanced imaging functions, suppressing noise in still images and movies, while reproducing excellent resolution, long tonal scale and vivid colour range.
