When we talk about low light action photography, we’re only speaking in relative terms, of course. There’s low light, and then there’s really, really low light … the kind of low light in which we can shoot the stars. If you’re interested in astrophotography, Canon and Nikon have both produced DSLRs that are optimised for the task. I believe the Canon EOS 20Da was the first DSLR specially designed for this purpose. Canon followed that up some years later with the Canon EOS 60Da. More recently, Nikon has produced the Nikon D810A—the newest mainstream DSLR for astrophotography.
Over the past few days, Adam Woodworth has had articles on the D810A published on Digital Photography Review (7 July) and Luminous Landscape (11 July). The first linked article has a selection of night landscapes, but the second linked article goes into detail about the technical capabilities of the D810A and the specific advantages it has over standard DSLRs for astrophotography.
If you’re interested in creating images of the night sky and have an interest in the technical aspects (including noise reduction in post-processing), take a look at the Luminous Landscape article.
