Nikon's D810A is an astrophotography-oriented version of the D810. It's the first full-frame camera dedicated to astrophotography, and is better able to capture the hydrogen alpha spectral line. It also expands long exposure options, and has garnered speculation as to improvements in low light capabilities. We've already published some impressions and real-world images, but now take a look at its performance in our studio.

Pay particular attention to Raw noise performance at high ISOs compared to its rivals - the results may surprise you. Our initial impressions suggest it's the new class leader with respect to high ISO performance in a 36MP+ full-frame body, which is quite a feat. And don't forget to look at color rendition, with the modified IR-cut filter. Do you note differences in JPEG or Raw color?
