Nikon D810A

Nikon D810A and 14-24mm f/2.8. (about $3,799, 34.0 oz./965g with battery and CF card). enlarge. I'd get it at B&H or at Adorama.

This ad-free website's biggest source of support is when you use that or any of these links to approved sources when you get anything, regardless of the country in which you live. Nikon does not seal its boxes, so never buy at retail or any other source not on my personally approved list since you'll have no way of knowing if you're missing accessories, getting a defective, damaged, returned, store demo or used camera. Buy only from the approved sources I use myself for the best prices, service, return policies and selection. Thanks for helping me help you! Ken.

Announced 10 February 2015, the Nikon D810A is the astrophotography version of the D810.

It changes the IR-cut filter to pass the hydrogen alpha line; it's four times as sensitive at 656 nanometers as the regular D810. Because of this filter modification, the D810A will give poor color rendition for normal photography, so you still need a regular DSLR for regular photography.

The D810A also has longer in-camera exposure settings to 15 minutes. (Nice, but so what; a stock F5 or F6 goes to 30 minutes.) All DSLRs ought to have shutter times to many minutes; but the makers prefer we have to purchase extra-cost remote releases and timers instead of simply putting longer exposures in the stock firmware for free. At least the D810A does go to 15 minutes.

ISO is from 200~12,800, 25,600 and 51,200.

Nikon's free Capture NX-D adds an option for Astro Noise Reduction for use with D810A files.

It should ship in late May 2015 to those who order it today.

The D810A is a D810 with a different IR-cut filter and slightly different firmware, otherwise it's the same camera.

Other than the spectral response, ISO range and long exposure time setting options, see my D810 Specifications for all the other specs.

You astro people know who you are. Canon has been offering the occasional astro version on and off for years, and now we can get an astro Nikon.

If you find my work helpful, my biggest source of support for this free website is when you use this link to get yours at B&H or at Adorama. When you use that or any of these links to approved sources when you get anything, regardless of the country in which you live, it helps me keep adding to this free website — but I receive nothing for these efforts if you take the chance of buying elsewhere.

Never buy something as specialized as this at retail, since you have no idea who's taken it out to play with. I get everything online because it all ships from automated warehouses with no salespeople getting their greasy fingers on it.

Thanks!

Ken.
