The Nikon D810A Is Targeted at Astrophotographers

D810A_14_24_front34l

Today, Nikon is announcing a brand new version of the Nikon D810: it’s being coined as the Nikon D810A and is targeted at Astrophotography. The secret behind the camera is a modification for the infrared cut filter for the hydrogen alpha wavelength–and it really targeted at both pros and hobbyists.

According to the press release:

“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.”

And while that is quite enough as it is, Nikon is packing in even more features for astrophotography. There is a new long exposure manual mode, has the same ISO sensitivity from 200-12,800, and adds a new visual exposure preview mode. At its heart is still a 36.3 MP CMOS sensor with an electronic first curtain shutter mode to minimize vibrations when shooting subjects like this.

Additionally, Capture NX now has a new Astro Noise Reduction feature.

Pricing will be announced later and availability will be late May 2015. Specs are after the jump.
