A Multi-CAM 4800 AF sensor is integrated into the camera's design and produces fast autofocus speeds using a 39-point array to precisely acquire focus in a wide array of lighting conditions. Seven of the central AF points are compatible with f/8 or faster lenses, which greatly enhances the autofocus performance with longer, telephoto lenses used in combination with teleconverters. When recording movies or working in live view, a contrast-detection focusing method works to continuously deliver accurate focus with subject-tracking and face-detection capabilities using the full-time servo mode.
Full HD 1080p video is supported up to 30 fps in the MPEG-4 AVC/H.264 format and manual control over the ISO, shutter speed, and aperture is possible for optimized control over the look and feel of movies. Uncompressed recording is possible with an optional external recorder connected via the HDMI port and, additionally, both headphone and microphone ports are available for refined control over recorded sound.
Extending the D610's connectivity, an accessory terminal is compatible with the optional WU-1b Wireless Mobile Adapter and GP-1A GPS Unit for wireless image sharing, remote camera control, and geotagging capabilities.
Included with the D610 body is the Nikon AF-S NIKKOR 28-300mm f/3.5-5.6G ED VR lens; a versatile wide-angle to telephoto zoom lens. This lens features VR (Vibration Reduction) to minimize the appearance of camera shake and also integrates two extra-low dispersion elements and three aspherical elements to minimize chromatic aberrations throughout the zoom range and enhance the overall clarity and contrast.
