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 On April 19, 2012, the D3200 superseded the D3100 as Nikon's entry-level DSLR.

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.Nikon D60 electronic rangefinder . Digital Photography Review. Retrieved on 7 September 2012.

Can mount unmodified A-lenses (also called Non-AI, Pre-AI or F-type) with support of the electronic rangefinder and without metering.John White's AI conversions for Nikon lenses Aiconversions

Reception The D3100 has received many independent reviewsDigitalcameratracker: Nikon D3100 reviews, ratings, sample photos Digitalcameratracker and image comparisons at all ISO speeds.Imaging Resource Comparometer (needs Javascript enabled)

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 (higher priced) Canon EOS 600D; lower than other current Nikon DSLRs.
