Nikon D850: First Look at Noise Under Field Conditions, Gross Underexposure

See my Nikon wish list and get Nikon D850 at B&H Photo.

What matters to me in a camera for my shooting is how it fares under real world conditions when pushed to its limits—that is, doing so is a proxy for what one can expect with less exposure 'abuse'.

Measurements of dynamic range do not speak to what I see for camera performance in real images. For example, pattern noise is not picked up by noise ratings, yet it can be the most crucial characteristic of the noise (not how much but its visual impact, like streaking/banding). Hence I like to see what a camera does when pushed hard: does it break down badly (pattern noise) or does it go noisy but not in an objectionable way.

Here the Nikon D850 is pushed beyond its limits with a 30 second exposure at late dusk where there is still light, but where it is getting too dark to hike without a flashlight. The glowing mountaintop was beautiful to behold, but also far brighter than the darker lake area.
