Nikon today announced its first full frame DSLR camera that is meant exclusively for astrophotography – D810A. As you can guess by the name, the D810A is based on the D810 model but comes with a different set of features and hardware tweaks that make it the ultimate astrophotography tool.
The D810A uses the same 36.3 megapixel full frame Nikon FX format CMOS sensor as the D810 and doesn’t include an optical low-pass filter. It also boasts of Nikon’s latest and greatest image-processing engine, EXPEED 4. To help users take great pictures of the stars and galaxies, the D810A includes a specially made optical filter that enabled ‘beautiful reproduction of vivid reds in images of nebulae that emit H-alpha light. The optical filter on the D810A is said to be capable of four times greater transmission of H-alpha light than the one used on the regular D810 model.
The other modifications Nikon has made with the camera include a long-exposure manual (M*) mode with exposure time of up to 900 s, live preview function to help focus and compose images, ability to enlarge the view through the lens displayed during live view by up to 23x for accurate focusing, electronic front-curtain shutter to help suppress mechanical shake, and an unlimited continuous shooting mode. All of these modifications make the D810A unsuitable for normal photography.
The D810A is said to arrive in stores by the end of May and will be priced at $3,799.95, which is $500 higher than what the regular D810 camera costs currently.
