The Nikon D3100 is a 14.2-megapixel DX format DSLR Nikon F-mount camera announced by Nikon on August 19, 2010. It replaced the D3000 as Nikon's entry level DSLR. It introduced Nikon's new EXPEED 2 image processor and was the first Nikon DSLR featuring full high-definition video recording with full-time autofocus and H.264 compression, instead of Motion JPEG compression. It was also the first Nikon DSLR to provide high-definition video recording at more than one frame rate. Use is assisted by two Guide Modes: Easy Operation and Advanced Operation tutorial. On April 19, 2012, the D3200 superseded the D3100 as Nikon's entry-level DSLR. ==Features== * Nikon's 14.2-megapixel Nikon DX format CMOS sensor with 12 Bit Resolution. * Nikon EXPEED 2 image processor. * Active D-Lighting. * Automatic chromatic aberration correction. * Sensor cleaning and airflow control system. * 3.0-inch 230,000-dot resolution fixed TFT LCD * Continuous Drive up to 3 frames per second. * Live view mode.
