I recently had the opportunity to spend some time (not nearly enough) with the D850 and compare its performance to other high-end Nikon cameras, especially as it pertains to night photography. Despite the moon, UPS and the weather (clouds, cold and wind) all conspiring against me, I was able to spend a couple of nights with the D850, as well as make some comparison images with the D750, D810, and D5.
There are many online reviews of the D850, but in this one I’ll focus entirely on how it performs and handles for night photography––in particular:
1. High ISO astro-landscape photography
2. Native ISO long exposure night photography
3. High contrast artificial light night photography
I am assuming that the reader is at least minimally familiar with Nikon DSLRs, and that they will use other resources such as DPReview and DXOMark to evaluate the camera for other types of photography.
Features and User Experience
The camera is just slightly heavier than the D810 and is well-balanced and comfortable to hold. It weighs about half a pound more than the D750, and almost a full pound less than the D5.
The controls and buttons of the D850 are similar to the D810, except that the ISO and Mode buttons have switched positions in line with the D5. This is a nice improvement over other Nikon cameras like the D750 where the ISO button is on the back and to the left of the display.
