The Nikon D850 DSLR camera not only produces 45-megapixel images perfect for landscapes and studio work, but its fast frame rate makes it potentially appealing for sports and action photographers. In sports and action photography, shutter speed is critical, and that means being able to push the camera ISO well above its base value. I decided to do some Nikon D850 high ISO testing to see how it fares.
The Nikon D850 has a base ISO of 64, but you can expand it up to 25,800. Beyond that, you can push the ISO two full stops (Hi 1 and Hi 2 settings) to get corresponding ISO values of 51,200 and 102,400, respectively. Nikon uses the “Hi” nomenclature to denote sensitivities that are not truly “in-spec” and in accordance with the ISO standard.
In my review of the Nikon V1, I subjectively rated ISO performance. It seems as though the first thing people want to do with any new camera is crank the ISO and then try to shoot in the dark (ok, I’m guilty, too). While ISO performance shouldn’t be the only judgment factor when purchasing a camera, it’s certainly true that being able to shoot at high ISOs absolutely opens up creative possibilities that didn’t previously exist. In fact, one reason I really enjoy walking around with my D3s is that I can set ISO-Auto and forget it!
