The Nikon D3100 is a 14.2 megapixel DX format DSLR Nikon F-mount camera announced by Nikon on August 19, 2010. It replaces the D3000 as Nikon's entry level DSLR. It introduces Nikon's new EXPEED 2 image processor and is the first Nikon DSLR featuring full high definition video recording with full time autofocus and H.264 compression, instead of Motion JPEG compression. It is 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.
Like Nikon's other consumer level DSLRs, the D3100 has no in-body autofocus motor, and fully automatic autofocus requires a lens with an integrated autofocus-motor. With any other CPU lenses the camera's electronic rangefinder can be used to manually adjust focus.
Can mount unmodified A-lenses (also called Non-AI, Pre-AI or F-type) with support of the electronic rangefinder and without metering.
The Nikon D3100 has available accessories such as:
