Nikon D3S SLR with 102400 ISO

[Paramvir Singh]

The D3s's sensor is an evolved form of the original D3's 12.1MP full-frame sensor, using a different structure to improve the signal-to-noise ratio while shooting at higher ISO ratings, along with new algorithms for better image processing. The normal ISO range is 200-12,800, going up to ISO 102,400 at the top end of the expanded range.

Creative Vision Beyond the Human Eye
The Nikon D3S, with a base ISO sensitivity from ISO 200 to 12,800 makes it possible to capture previously impossible images-image opportunities which were often ignored because of low light levels. Now, in even more demanding lighting conditions, photographers can select expanded sensitivity settings of ISO equivalent 25,600, ISO equivalent 51,200 and an incredible ISO equivalent sensitivity of 102,400 which reveals detail in extreme low-light environments that challenge even the human eye's ability to discern subject content. In addition, a setting of ISO equivalent 100 is provided.

This industry-first, groundbreaking ISO sensitivity range will make the D3S the camera of choice for photographers who typically face extreme lighting challenges, such as indoor or nighttime sports, spot news, wedding receptions and ambitious nature photography. This broad ISO sensitivity also affords the ability to shoot at faster, action-stopping shutter speeds. D3S shooters will enjoy a major advantage in any situation where light is limited and the use of supplemental lighting is not an option. For the photojournalist, even the highest ISO setting delivers image quality to satisfy the needs of offset printing.

Big Pixels Equal Greater ISO Capabilities
The amazing low-light ability of the D3S, as well as its astounding image quality can be attributed in large part to the engineering behind the newly designed, Nikon original 12.1-megapixel FX-format CMOS sensor, which measures 36x23.9mm. While the pixel size and count that served the D3 were maintained to deliver the pinnacle of image quality, dynamic range, phenomenal tonal gradation and outstanding color, other aspects were engineered to add versatility through broader low-noise ISO sensitivity. Individual pixels measure a large 8.45 microns, which support enhanced sensitivity to light and other qualities leading to superior image fidelity. The D3S captures light and renders images in a way that no other Nikon camera has yet to achieve, with a higher signal-to-noise ratio and an unmatched dynamic range for both stills and HD video throughout its broadened ISO range.

D3S adds the extra benefit of an Image Sensor Cleaning function to reduce instances of image degradation resulting from dust accumulation on the optical low pass filter (OLPF) in front of the image sensor. The OLPF oscillates at four specific frequencies to release particles that would disrupt image quality. Sensor Cleaning can be set by the user to cycle automatically when the camera is powered on, turned off, or on demand.
