Multi-CAM 2000 Autofocus Sensor Module
Nikon’s Multi-CAM 2000 AF sensor module has an 11-area sensor for
the most practical coverage. Its nine cross-type sensors are spread
wide across the frame, as opposed to being bunched in the center.
No matter how fast your subject moves one of the sensors is sure to
track it. All nine cross-type sensors are fully operational with any AF
Nikkor lens — a big advantage for photographers. These sensors are
also superior in defocus detection, allowing the camera to assign
appropriate focus points quickly and efficiently.
Most AF systems use only one CCD, but the Nikon system
uses three to extract the utmost precision from each of
the nine cross-type AF sensors.
