Specifically developed for those looking to capture images of the night sky, the Nikon D810A is a modified D810 featuring an optical IR cut filter for capturing far off nebulae and other astronomical phenomena with the ultimate clarity and color accuracy. By enhancing the design of the D810 with a filter specifically designed to pass H-alpha (656.28nm) wavelengths, the D810A has the capability to depict nebulae and other subjects without undesirable
infrared contamination for enhanced color neutrality. Taking advantage of this sensor filtration adjustment, this specialized Nikon D810a also offers an expanded shutter speed spectrum and new M* exposure technique for more accurate exposure times as long as 15 minutes, as well as a
Virtual Live Exposure Preview mode to aid in clear composition and focus confirmation when capturing such long exposures. Beyond these minor but notable distinctions, the D810A and D810 contain the same core feature set to produce high resolution, well-detailed images.
The D810A contains a 36.3MP FX-format CMOS sensor less an optical low pass filter for particularly crisp and detailed still images. Since the upgrade to the EXPEED 4 Image Processor, execution speed is enhanced compared to the EXPEED 3 while noise is effectively diminished all through the ISO range. Continuous shooting speed using FX format is 5 frames per second and in DX format attains a maximum of 7 frames per second. In addition, the full HD video capabilities include capturing 1080p at 24, 30 and 60 frames per second. Also, the improved efficiency of the processor permits up to 1200 shots on a single battery charge and 40 minutes of video capturing.
Low light operation has been upgraded thanks to a
broad native sensitivity range that runs from ISO 200 thru 12800 and is expandable from ISO 32 thru 51200. Additionally, as a camera also optimized for acquiring video, the D810A can record in both FX and DX formats including simultaneous capture to memory cards plus use an external recorder as well as capturing 60p output to an external recorder.
The 3.2", 1,229k-dot resolution LCD provides crisp playback viewing along with live view, and enhanced coatings on the optical viewfinder components deliver brighter images and more precise colors. Live View mode now includes split screen display zoom for still photos, and zebra highlighting display when using video recording. Full aperture metering using live view for still photography is supported. Interval and time-lapse photography feature exposure smoothing, while the maximum number of shots per sequence is now 9,999. In addition, the D810A makes use of dual media slots featuring both Compact Flash and SD cards for increased image storage capacity or automatic file back-ups in-camera.
