Nikon's entry-level APS-C DSLR with 14.2MP sensor, HD video, and guide mode for complete beginners.
The Nikon D3100 launched in 2010 as Nikon's most affordable DSLR, featuring a 14.2MP APS-C CMOS sensor, Full HD 1080p video recording, and an innovative Guide Mode that walks beginners through camera settings with on-screen instructions.
The 14.2MP CMOS sensor delivers good image quality with clean results to ISO 1600. 11-point AF system with single cross-type centre point. 3fps burst shooting. 1080p 24fps video — the first D3x00 to record Full HD. EXPEED 2 processor. Live View with contrast-detect AF.
Lightweight plastic body at 455g. 3-inch fixed LCD at 230k dots. Single SD card slot. Built-in flash. No built-in AF motor — requires AF-S or AF-I lenses for autofocus. Guide Mode provides interactive shooting advice on-screen.
Extremely common and very cheap used. The lack of built-in AF motor limits lens compatibility to AF-S lenses. The D3200 improved to 24MP and the D3300 is the sweet spot of the series. Guide Mode is genuinely helpful for first-time users. An affordable introduction to Nikon DSLR photography.
