Realizes high resolution and smooth tonal gradation —
Nikon DX-format CMOS sensor
16.2 effective megapixels. The D5100 employs Nikon DX-format CMOS sensor equivalent to that of the higher-class model, D7000. It achieves high resolution reproduction and smooth tonal gradation, as well as a wide ISO sensitivity range of ISO 100 to 6400 that is expandable to Hi 2 (ISO 25600 equivalent), high-speed readout during Live View, and full HD movie recording.
Gets the most out of the performance of the CMOS sensor —
image processing engine "EXPEED 2"
The D5100 incorporates image processing engine "EXPEED 2" that is equivalent to that of the higher-class model, D7000. It realizes noise reduction in shooting at high sensitivity range, improved color reproduction, high-speed image processing and efficient energy saving, getting the most out of the performance of the CMOS sensor in shooting still images and movies.
Effective for low-light situations and moving subjects —
ISO sensitivity up to ISO 6400
Wide sensitivity range of ISO 100 to 6400. It can be raised up to Hi 2 (ISO 25600 equivalent). Even at high ISO setting, sharp images are delivered with minimized noise while maintaining resolution. Setting high ISO sensitivity enables you to shoot at faster shutter speeds and capture pictures without worrying about image degradation caused by camera shake even in low-light situations or when shooting a moving subject. Furthermore, this superior high-sensitivity performance is effective for D-Movie and you can shoot beautiful movies without large-scale lighting equipment even in low-light conditions.
Provides images with rich tonal gradation even in high-contrast scenes —
HDR (High Dynamic Range) [NEW]
Two images taken with one shutter release at varying exposure are combined to produce a single image that has a wider dynamic range (range of contrast to reproduce tonal gradation) with less loss of detail in highlights and shadows. The result is images with less noise and rich tonal gradation throughout the entire frame including shadows and highlights even in high-contrast shooting scenes. Exposure differential is selectable from Auto, 1 EV, 2 EV and 3 EV*. The boundaries between the two images can be smoothed (the degree is selectable from High, Normal and Low). Suitable for stationary subjects such as landscapes and still lifes.
- *Can be expanded up to 5 EV equivalent when combined with Active D-Lighting.
Note: Recommended to use a tripod.
Reproduces brightness as you see it — Active D-Lighting
Active D-Lighting is effective for shooting, for example, a dark room including outside scenery seen through a window, high-contrast scenes such as at the seaside under strong sunlight, and backlit situations. It preserve details in both highlights and shadowy areas in such situations, maintaining moderate contrast to reproduce brightness as you see it. Select the preferred setting from "Auto", "Extra high", "High", "Normal", "Low" or "Off". Active D-Lighting works for a moving subject and it is also possible to bracket images so as to obtain one with Active D-Lighting and another without.
