Note: These images are pre-production samples from the Nikon D3, shot in 2007 prior to the camera's release.
Here are some new samples from the Nikon D3, coming to you from the IFA electronics show in Berlin. The following images were shot and graciously provided by dpreview.com member grizerep19, who was able to attend the German expo and spend a little time with the D3.
UPDATE: grizerep19 has uploaded the complete set of uploaded a few full-resolution images. All of the following crops are at 100%.
ISO 1600: 100% crop
ISO 3200 (resize)
ISO 3200: 100% crop
ISO 6400: 100% crop
ISO 25600: 100% crop
The above images were shot with the Nikon 50mm f/1.4 at maximum aperture with the exception of the ISO 1600 shot, which was made at f/2.8.
Many thanks to grizerep19 for supplying these samples, which make a nice addition to the other high ISO 100% crops available, which together begin to describe the noise characteristics of the D3. Overall, the noise appears largely luminance-based, rather than of the chroma variety, which is generally typical of Nikon's DSLRs. However, the D3 appears to produce files at high ISO with a level of quality never seen before in a Nikon.
