Great Tonal Range and Color Accuracy
I switched from a D800 to the D850 and was amazed at the improved tonal range and color accuracy of the D850. When I calibrated the color using DataColor Spyder Checker the profile only adjusted a few of the color swatches by 1 or 2. The images I get over the D800 just seem to pop without any adjustment. The high ISO capability of this camera is just outstanding. I´ve used it several time to shoot some concert photos in an auditorium at 4000 to 25,400 ISO and the images look great even without applying any noise reduction. The image sharpness and detail is a significant improvement over the D800. I shot some birds of prey using a tripod and a calibrated lens (Sigma 150-600mm) and every line and strand of their feathers is razor sharp. I thought the D800 was a fantastic camera. Such and improvement in all areas.
