Design and Ergonomics
The Nikon D3100 has dimensions of 124 x 96 x 74.5 mm and a weight of 455g.

Live View - Live View with new AF modes and large 7.5-cm (3-in.) monitor
Live View gives you an intuitive, familiar way to photograph playful pets or children on the move. Just flip a switch and you're ready to go. When Live View is activated and new full-time-servo AF (AF-F) is selected, the camera keeps subjects in focus without having to press the shutter-release button - convenient for photos and movies. There is also new face-priority AF that locks focus on faces, even on people not directly facing the camera. Live View makes D3100 as easy to use as a compact camera.

AF Mode for Live View and Movie Shooting
Three AF modes - single-servo AF (AF-S), full-time-servo AF (AF-F) and manual focus (MF) - are available when using Live View or shooting movies. For movies, use AF-F with subject-tracking AF. These help maintain focus on a selected subject and work together to continuously track a subject as it moves through the frame, realizing camcorder-like focusing.

Picture Quality
Nikon equipped D3100 with a newly developed CMOS sensor for outstanding subject detail and smooth color gradation. Whether shooting photos or full HD movies, the sensor is crucial to image quality. The high pixel count of D3100's sensor produces photos of striking clarity, revealing all the nuance of the original scene with minimum noise - ideal for intricately detailed textures and grain-free background defocus.

With 14 megapixels you can acheive 11x14 print at full resolution with room for cropping and with greater enlargement possible to achieve high quality banner size prints

Welcome to a new level of excellence with EXPEED 2. We've leveraged our vast technological know-how to bring you Nikon's most advanced image processing engine yet. EXPEED 2 maximizes CMOS sensor performance for clear, lifelike images that exhibit vivid colors, reduced noise and smooth tonal gradations for outstanding photos and movies.

Performance Features
A maximum ISO of 3200 (standard range) lets you shoot at fast shutter speeds, reducing camera-shake blur in dimly lit scenes. Twilight and indoor shots come alive with a refreshingly natural look without the need for a tripod or flash. Moreover, fast shutter speeds make it easy to freeze action in dynamic situations such as children at play and sports events. For added versatility, D3100's Hi 1 and Hi 2 settings effectively boost ISO to the equivalent of 6400 and 12800, respectively.

D3100's precision high-speed autofocus responds immediately to changes in scene or composition, maintaining tack-sharp focus to capture fleeting expressions and fast-moving sports. The all-important central focus point features a cross-type sensor while the new superimposed display achieves a clear, uncluttered viewfinder. Various autofocus modes cover nearly any situation, including auto-area AF that automatically selects the subject on which to focus, and 3D-tracking (11 points)* that maintains focus on a subject regardless of changes in composition as long as the shutter-release button is pressed halfway.

Technology Features
Scene Recognition System - Intelligent operation in any setting
Nikon's exclusive Scene Recognition System utilizes a 420-pixel RGB sensor to analyze a composition immediately before you take the shot. It then automatically optimizes exposure, autofocus, and white balance, allowing you to obtain beautiful photos without the hassle of making complicated camera adjustments yourself. Face detection also benefits from Scene Recognition System, exhibiting improved recognition accuracy and definition as well as enabling instant zoom-to-face in playback mode. playback of footage and images on any HDTV. With HDMI enabled TV sets playback can be controlled using the remote control.

D-Movie - Breathtaking full HD 1080p movies
Discover the difference a digital SLR makes when shooting movies. A wide selection of NIKKOR lenses gives you freedom to explore different angles and obtain lovely defocused backgrounds while D3100’s advanced imaging system assures outstanding quality. And for action sequences, new Subject-tracking AF keeps subjects properly focused.
After the shoot, view movies on the large 7.5-cm (3-in.) LCD monitor and perform simple editing tasks like trimming scenes before or after a designated point and extracting still images. HDMI compatibility* lets you connect D3100 to an HDTV with playback managed by the TV’s remote control

Expression - Ample image and movie editing functions - In-camera image and movie editing
Heighten your photographic enjoyment with D3100's wide range of image and movie editing functions. Operations like Red-eye correction, Quick retouch, and Filter effects can be done in-camera via the Retouch menu, eliminating the need for a PC and enhancing convenience. You can also extract still images from movies and trim unnecessary frames.

This popular 3x zoom lens with high quality optics and Nikon’s exclusive Silent Wave Motor (SWM) for super-quiet operation, has a focal length equivalent to 27-82.5mm in 35mm format - making it a good standard lens to cover your basic shooting needs.

Differing from the Nikon 18-55mm F3.5-5.6 II AF-S DX, this lens features a Vibration Reduction (VR) stabilization system, enabling sharper pictures while shooting at shutter speeds up to three stops slower than would otherwise be possible. Its aspherical lens elements minimize spherical aberration, astigmatism, and other forms of distortion, while ensuring high resolution and contrast. Basic Features Minimum Aperture: f/22-36 Closest focusing distance: 28cm Dimensions: 73 x 79.5mm Weight: 265g Filter Diameter: 52mm Nikon 55-200mm VR This lens is purpose built for Nikon DX format SLR cameras providing a 35mm equivalent focal length range of 82.5- 300mm,which is a perspective from normal to standard telephoto for general telephoto photography and portraits. VR (vibration reduction) is an optical image stabilisation system that uses microgyro sensors to analyse camera shake and shift elements in the lens in response, ensuring sharp images at slow shutter speeds, ultimately providing a gain of up to 3 stops over non-VR lenses. An excellent feature for capturing detail in low-light conditions. One ED element helps to minimise chromatic aberration, astigmatism, and other forms of distortion, while ensuring high resolution and contrast. Nikon's exclusive SWM (Silent Wave Motor) delivers fast, precise, and super-quiet operation. Basic Features Minimum focus distance: 1.1m Minimum Aperture: 22-32 Filter Size (Ø) = 52mm
