Some more Nikon D5 sample photos (both JPG & NEF) as many readers already have the D5 in their hands:
First, Ole Liodden updated his Nikon D5 review and he is "shocked":
"Today I installed the new Lightroom and Camera RAW software supporting the Nikon D5 camera and I could finally view the NEF-files from the beta testing September-November 2015, and I’m shocked. The image quality at ISO 32 000 is not as stated below only “promising” but very, very good. The sharpness and low noise at ISO 25 000+ is better than I could see in the jpg-files. The test report below was written in mid January when I only could view the JPG-files. All exposures were done in NEF + jpg format."
ISO 409,600 (only D5)
ISO 819,200 (only D5)
ISO 1,638,400 (only D5)
ISO 3,276,800 (only D5)
Dpreview also posted their Nikon D5 studio test online.
