HOME > AF & AE

$“With high-speed continuous shooting of 9 frames per second (approx.), each frame is allocated about 111 milliseconds. Between exposures, within the smallest window of time, metering, focusing and white balance operations are carried out sequentially before high-speed lens driving for autofocus is implemented. All operations take place smoothly and accurately. Nikon's goal is to offer real-world automatic control that cannot be achieved by theory alone. It's quality that can only be successfully attained through relentless, repeated test shootings.” Using 51 focus points, the largest number of any camera system*, the subject is quickly captured, then accurately and continuously tracked. But AF operation is not simply the result of the AF system alone. It is also supported by the Scene Recognition System’s subject identification and tracking information, thereby enhancing subject detection and focusing performance. What’s more, accurate color information from the 1,005-pixel RGB sensor combined with the sophisticated new diffraction grating improves the overall precision of auto exposure and Auto White Balance. These highly accurate automatic controls work constantly, even when performing high-speed shooting with the D3 is running at 9 frames per second. Furthermore, for the first time in any digital SLR camera*, Nikon has incorporated a contrast-detect AF system that delivers the degree of accurate focus that still-life photographers demand. Nikon’s broad spectrum of technologies are based on a rigorous, time-tested expertise that will enhance the shooting abilities of any photographer. * For D-SLR cameras (as of Aug. 23, 2007, based on Nikon research)$
