Nikon D300s Digital SLR - Test Shots – ISO Performance Review

”A range of test shots are shown over the next few pages. Here, the full size images at the minimum and maximum ISO settings have been reduced for bandwidth purposes to let you see the full image, and a series of crops taken from original full resolution images at a range of ISO settings have been included in order for you to gain an appreciation of the overall quality. ”

This is the full frame at 100 ISO, and extended setting. The normal minimum setting for the D300s is 200 ISO.

Flawless image quality at 100 ISO.

A rare mistake by the Nikon’s AF system here, but still no noise at 200 ISO.

There is a tiny hint of colour mottling at 400 ISO, but no real noise problems.


—-


Very similar results at 800 ISO.


—-


Picture quality is still excellent at 1600 ISO.

3200 ISO is the normal maximum, and image quality is certainly good enough for a smaller print.

Extended to 6400 ISO image quality is badly affected by noise reduction.

This is the full frame at 6400 ISO. At this size it looks fine.
