The D810A Provides New Features Specifically for Astrophotography
I AM Star Struck: DSLR Optimized for AstrophotographyThe Nikon D810A provides hobbyists as well as professional stargazers with a powerful combination of impressive resolution and features specifically created for astrophotography and scientific applications. The infrared (IR) cut filter has been optimized to allow transmission of the hydrogen alpha spectral line, resulting in four times greater sensitivity of the 656nm wavelength. The resulting images capture the brilliant red hues of diffuse nebulae and constellations in striking detail and fidelity. While not recommended for general photography, the D810A is an excellent option for photographing the universe with either NIKKOR lenses or third-party adaptors for telescopes.In addition to the optimized IR cut filter, the D810A adds other features that are useful for astrophotography applications. A new Long Exposure Manual Mode is implemented, giving users the ability to set shutter speeds from 4, 5, 8, 10, 15, 20, 30, 60, 120, 180, 240, 300, 600 or 900 seconds (15 minutes), as well as Bulb and Time settings. Building upon the D810’s excellent low-light capabilities, the ISO range has been optimized from 200 to 12,800 (Hi-2 51,200), for maximum sensitivity with the optimal signal to noise ratio.The D810A also adds a new Virtual Exposure Preview Mode, which displays an estimated preview image and is available when shooting at shutter speeds longer than 30 seconds when in Live View. The brightened preview image represents a 30 second exposure, simplifying focusing and composition.
The Best of Both WorldsThe Nikon D810A is based off of the Nikon D810 architecture and retains all of the features that make it a powerful tool for creating images. Users will be able to produce photos of the heavens in super high resolution thanks to the 36.3-megapixel CMOS sensor. The image sensor works in tandem with Nikon’s exclusive EXPEED 4 Image processing engine to deliver images with low noise and a dynamic range that is nothing short of stellar. The D810A also features an Electronic Front Curtain Shutter Mode, letting the electronic front curtain act as a shutter when in live view or first composing through the optical viewfinder in mirror-up mode. This feature minimizes vibrations to attain maximum sharpness when shooting subjects at very slow shutter speeds. The camera also features a durable magnesium alloy body that is sealed against dirt and moisture, giving users peace of mind when getting away from the city lights means a trek off of the beaten path.The Nikon D810A is compatible with a wide range of high quality NIKKOR lenses and accessories, including wireless infrared remotes, cable releases and the new WR-1 wireless remote system. Additionally, Nikon’s Capture NX-D software is available as a free download, and it will feature a new option for Astro Noise Reduction for use with D810A image files.
