Our least expensive Nikon intro level camera the D3100 has a 14.2 Megapixel CMOS crop sensor (DX) with 14-bit conversion as the D7000. It also has a nice 3 inch LCD monitor, and shoots 1080p HD video at 24 FPS with full time autofocus.
It has ISO sensitivity of 100 to 3200, and 11 point autofocus system, and can create in-camera HDR (high dynamic range) images for those of you who aren’t over that yet. It also has the usual Nikon goodies: 3D Color Matrix Metering, Scene recognition and gobs of in-camera special effects. It shoots at a maximum of 3 frames per second and has an electronic rangefinder for focusing under difficult low-light conditions. A great camera for beginners, the menu has a very nice built-in help section and the camera and easy to use “guide mode”.
This camera will only provide autofocus with lenses that have a built-in AF motor.
