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'.

In Nikon D850: First Look at Noise Under Field Conditions, Gross Underexposure, I looked at gross underexposure. In this example, I look at a 15 second near-optimal exposure.

Nikon D850: Noise: 15 Seconds, Near-Optimal Exposure (Rock Creek, Late Dusk)

Includes images up to full camera resolution as well as RawDigger histograms.

NIKON D850 + Zeiss Milvus 18mm f/2.8

[low-res image for bot]

Jason W writes:

I agree with your observations about the undesirable subjective quality of the noise compared to the D810. However, the quality of the Milvus 18mm glass really shines in this image.

While the DR improvement didn't materialize, the extra pixel advantage seems to be there for optics that can utilize it. Subjectively in total, it is very pleasing to me.

DIGLLOYD: agreed.
