Nikon D3100 Digital SLR Camera Body Only

Nikon D3100 Digital SLR Camera Body Only An entry level digital-SLR camera with a new CMOS image sensor, image-processing engine and helpful Guide mode that makes capturing beautiful images easy.

A new DX-format CMOS image sensor and image-processing engine
The D3100 is equipped with a new Nikon DX-format CMOS image sensor and a new image-processing engine, EXPEED 2, both developed by Nikon. The CMOS image sensor offers an effective pixel count of 14.2-million pixels (D3000: CCD image sensor with 10.2-million effective pixels) and enables capture of high-definition images exhibiting superior image quality with extremely detailed rendering and rich tones. The camera also makes the most of its standard sensitivity settings up to ISO 3200 (D3000: ISO 100–1600) and additional increases up to Hi 2 (ISO 12800 equivalent), with shooting under dim lighting, such as in the evening or indoors, as well as with sports scenes of rapidly moving subjects.

Assist images
The D3100 displays assist images that show the effect of various camera settings, giving users an idea of the results they can expect with specified settings. For example, when Soften backgrounds is selected and an aperture value is specified, the assist image displayed in the monitor changes to show the effect that aperture setting will have on images. This allows users to confirm that images will appear as they intended prior to shooting and reduces the number of unsuccessful shots.

Other new functions built into Guide mode
Selection from 3 shooting techniques: Use the viewfinder,Use live view,Shoot movieBring more into focus and Show water flowing options have been added to the Advanced operation menu for shooting Movie settings,HDMI,Flicker reduction and Eye-Fi upload options have been added to the Set Up menu for applying basic camera settings

Live view mode that allows users to use the camera monitor to easily frame still image or movies
By simply rotating the live view switch, the view through the lens is displayed in the monitor, enabling immediate live view recording. This makes shooting feel more like shooting with a compact digital camera, easing the transition to digital-SLR for beginners. In addition, various information such as the shooting mode, time remaining and battery indicator, can be shown in the live view display

D-Movie for recording and editing full-HD movies and AF-F  focus mode for movie recording
The D3100 is equipped with the D-Movie function that enables recording of high-definition movies  by simply pressing the movie-record button. Movies can be recorded with the same aperture and other settings applied in Guide mode, and movies that take full advantage of the characteristics of individual interchangeable lenses, whether wide-angle, telephoto or fisheye, can be recorded for movies that are only possible with a digital-SLR camera. In addition, the camera also offers an AF-F  focus mode for movie recording. When AF-F mode is enabled, the camera focuses continuously during movie recording without the need for holding the shutter-release button down halfway.

Scene auto selector built in
The D3100 is equipped with the scene auto selector function. When live view mode is enabled in Auto or Auto  mode, the camera automatically analyses the scene and selects the appropriate shooting mode from Portrait, Landscape, Close up or Night portrait. This function allows users achieve the intended images while leaving all settings up to the camera.
