Nikon D3100


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 On April 19, 2012, the D3200 superseded the D3100 as Nikon's entry-level DSLR.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

Like Nikon's other consumer-level DSLRs, the D3100 has no in-body autofocus motor, and fully automatic autofocus requires one of the currently 162 lenses with an integrated autofocus-motor. With any other lens, the camera's electronic rangefinder can be used to manually adjust focus.
Can mount unmodified A-lenses with support of the electronic rangefinder and without metering.

Optional accessories

The Nikon D3100 has available accessories such as:
The D3100 has received many independent reviews and image comparisons at all ISO speeds.
The D3100 is the only known Nikon DSLR with an image sensor interface integrating analog-to-digital converters not made by Nikon: The result is a dynamic range only at the level of competitors like the Canon EOS 600D; lower than other current Nikon DSLRs.
