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?
