The Nikon D610 DSLR Camera features a full-frame, FX-format 24.3 megapixel CMOS sensor and EXPEED 3 image processor to produce high-resolution still imagery and full HD 1080p video with notable image detail and low-light sensitivity to an expandable ISO 25600. The sensor and processor work together to enable high image quality with a wide dynamic range and high signal-to-noise ratio that produces both smooth color and tonal gradations with low noise levels for enhanced overall clarity. These two technologies also combine to provide a wealth of speed throughout the D610, including a continuous shooting rate of 6 fps and a quiet shooting mode that allows the camera to record sequential imagery without the mirror raising or lowering. 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.
