Nikon D610 Body Only Digital SLR Cameras
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.
24.3MP FX-Format Sensor and EXPEED 3 Image Processor
The 24.3 megapixel full-frame (FX) CMOS sensor and EXPEED 3 image processor work in tandem to produce overall high image quality with notable detail, dynamic range, color accuracy, and low-light sensitivity to a native ISO 6400, which is further expandable to ISO 25600. The processor also enables a wealth of speed throughout the camera system, including support for full HD 1080p movie recording, a full-resolution continuous shooting rate of 6 fps, and a continuous quiet mode for recording a sequence of images at 3 fps without the raising and lowering of the camera's reflex mirror. The sensor can also record imagery in DX format and will automatically switch to and support the use of DX-dedicated lenses when attached.
Multi-CAM 4800 Autofocus Sensor
Benefitting the exceptional image quality is an apt AF system that employs 39 distinct AF points to quickly acquire focus in a range of lighting conditions, from -1 to +19 EV. An intelligent Scene Recognition System, typically reserved for exposure metering, benefits the focusing performance by analyzing and identifying subjects to suit panning and tracking-based shooting styles. Depending on the situation, 9, 21, or 39 point arrays can be selected from and seven centrally-located AF points are compatible with f/8 or faster lenses, extending the auto focusing abilities of the longest lenses used in conjunction with teleconverters. When using this phase-detection focusing method, selectable AF-area modes include: Single-point AF mode, Dynamic-area AF mode, 3D-tracking mode, and Auto-area AF mode.
When working in live view, for either still or movie shooting, a contrast-based AF system is employed to acquire focus precisely and can function in continuous, full-time servo mode to better-suit working with moving subjects. Four distinct AF-area modes are available when using the contrast-detection focusing method: Face-priority AF, Wide-area AF, Normal-area AF, and Subject-tracking AF.
Scene Recognition System and Exposure Metering
The intelligent Scene Recognition System with 3D Color Matrix Metering II utilizes a 2016-pixel RGB sensor to evaluate and analyze all aspects within a scene, including brightness, contrast, subject distance, and the scene colors, to quickly determine an accurate exposure and white balance setting to best render the scene at hand. The information gathered is also checked against onboard reference images to ensure consistency from image to image in regard to exposure, white balance, i-TTL flash settings, and subject-tracking AF performance.
Full HD 1080p Movie Recording
Full HD 1920 x 1080p movie recording is supported in 30, 25, and 24 fps frame rates, as well as HD 720p in multiple frame rates, in the MPEG-4 AVC/H.264 format. During recording, manual exposure control is possible through adjustment of the ISO, shutter speed, and aperture setting and full-time autofocus can be employed, with face-detection and subject-tracking capabilities.
For enhancing the sound of recordings, both an external microphone input is available as well as a headphone jack for real-time monitoring of recorded sound. An HDMI output is also incorporated into the design and, besides enabling HD playback of video, also supports uncompressed recording of HD video by using an optional external recorder. Regardless of the lens in use, multi-area full HD D-Movie enables you to choose between FX or DX recording areas of the sensor to modify the composition and gain additional reach from lenses, as well as expanded control over the depth of field.
Built-In Pop-Up Flash and i-TTL Support
The built-in pop-up flash extends its functionality beyond acting as a source of additional light by also serving as a wireless Commander, capable of communicating i-TTL exposure information to two groups of remote flashes across three channels for refined control over strobe lighting. A hot shoe is also available and supports Nikon i-TTL and Creative Lighting System with compatible optional Speedlights.
Even with a large FX-format sensor inside, the D610's overall form-factor remains relatively compact and lightweight, enhancing its portability and travel potential. Beside the optical pentaprism viewfinder with 100% frame coverage and 0.7x magnification, a 3.2" 921k-dot LCD monitor is available for clear, bright image playback, menu navigation, and live view monitoring. Dual SD memory card slots support a range of recording capabilities, including overflow recording and JPEG/RAW partitioning.
An accessory terminal supports the use of the optional WU-1b Wireless Mobile Adapter for Wi-Fi sharing of images and video as well as remote camera control from a linked iOS or Android device with the Nikon Wireless Mobile Adapter Utility application. The GP-1A GPS Unit is also supported for adding locational data to images' metadata for geotagging applications.
