The Nikon D3100 is an APS-C DSLR built around a 14MP sensor powered by the EXPEED 2 image processor, making it a solid entry point into interchangeable-lens photography. It shoots stills at a maximum resolution of 4608x3072 pixels and offers a burst mode at up to 3 frames per second — enough for casual action and everyday shooting. The autofocus system is an 11-point Multi-CAM 1000 phase-detection setup, providing reliable focusing across a range of subjects.

ISO sensitivity runs from 100 to 3200, giving workable flexibility in varied lighting conditions. On the video side, the D3100 records at 1080p up to 24fps in 8-bit color, with a Standard color profile. Composition is handled through an optical pentamirror viewfinder, while the rear features a 3-inch LCD at 230,000 dots for image review and menu navigation.

Storage uses SD, SDHC, and SDXC cards. Connectivity includes USB and an HDMI Type C output for external display. The polycarbonate body measures 124 x 96 x 74.5 mm and weighs 455g, and it includes a built-in pop-up flash.
