The evolution of a masterpiece. The course of modern imaging has been forged by the talent and ingenuity of working professionals, but also by the introduction of a few cameras so innovative and forward-thinking, they redefined what's possible. The Nikon D4 has been such a camera. And now D4S proves that a great thing really can get better, with remarkable enhancements throughout the entire workflow, dazzling new levels of speed, performance, ISO sensitivity and, of course, the superior image quality of a Nikon camera. Speed and performance How do you make a revolutionary camera better? Improve its speed, precision and efficiency without sacrificing the features that make it exceptional. D4S builds on the success of D4 with 30% faster image processing and substantial energy savings-capture up to 3,020* stills on a single charge-an extended standard ISO range (100-25,600) with enhanced noise reduction, and improved tonal range and smoother gradations. Shoot 11 fps for approx. 200 shots at full resolution with AE and AF functionality. For faster initial subject capture, use five AF sensors as a single focus point with the new Group Area AF setting. Transfer files faster than the D4 with new 1000 Base-T (Gigabit) wired LAN, and increase that speed further by shooting a new smaller RAW SIZE S format. Perform at your peak-D4S will keep up. Nikon image quality Like its predecessor, the D4, the D4S delivers a level of image quality that elevates the power of any story. An improved 16.2MP FX-format CMOS image sensor is paired with Nikon's spectacular new image-processing engine, EXPEED 4, for truly phenomenal speed and performance in the field. The combination achieves outstanding ISO sensitivity, faithful, vibrant color, natural depth, subtle nuanced tones from pitch black to snow white and smoother gradations in both stills and videos.
