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.
Other Camera Features
- Picture Control modes can be directly accessed via a dedicated button and allow you to set predefined looks to imagery in-camera, and include Landscape, Monochrome, Neutral, Portrait, Standard, Vivid, and user-customizable settings.
- An intelligent noise reduction method analyzes the noise appearing in an image or movie and then automatically determines the proper amount of correction to apply in order to maintain the best balance of noise and image detail.
- Auto ISO sensitivity control allows you to select a minimum shutter speed at which camera shake can be controlled from and then will automatically set the ISO value in order to best render the scene. A maximum sensitivity level can also be set in order to maintain overall noise levels.
- RAW (NEF) files can be recorded as lossless compressed or compressed at either 12 or 14-bit depth.
- Active D-Lighting helps to preserve both highlight and shadow details when working in contrast-rich scenarios, such as backlit lighting. Utilizing the EXPEED 3\"s processing power, a more controlled image will be produced with brightness values closer to how they are naturally seen. This mode is suitable for working with moving subjects.
- Built-in HDR works to extend the tonal and exposure range of a single image by recording two separate exposures and blending them together in order to gain greater highlight and shadow details with an extended range of mid-tones. The smoothness of the edge where the two separate exposures meet can be adjusted for more apparent softness to benefit images with a greater range of exposure values. This mode is best suited for working with stationary subjects.
- Automated time-lapse photography allows you to record images at designated intervals and then have them automatically saved as a video file for fluid playback of a slow-motion activity occurring over time.
- Lateral chromatic aberration reduction, auto distortion control, and vignette correction are all supported when a NIKKOR lens is attached and work to reduce these optical anomalies in-camera for higher quality imagery.
- An in-camera virtual horizon can detect both rolling (horizontal inclination) and pitching (forward or rear inclination) directions and display an electronic level on the LCD when working in live view. The rolling direction of tilt can also be displayed within the viewfinder.
- Top and rear covers are constructed from magnesium alloy for a lightweight, yet rigid and durable body design that maintains dust-prevention and water-resistance performance. The interface covers are also designed in a divided manner to further ensure dust- and weather-protection to this ports.
- The highly precise and durable shutter mechanism has been tested for 150,000 cycles and incorporates a self-diagnostic shutter monitor to maintain precision with minimal shutter speed variance.
- Scene modes: Portrait, Landscape, Child, Sports, Close up, Night portrait, Night landscape, Party/Indoor, Beach/Snow, Sunset, Dust/Dawn, Pet portrait, Candlelight, Blossom, Autumn colors, Food, Silhouette, High key, and Low key
