The Nikon D4s Digital SLR Camera is a professional flagship camera with a full frame sensor, massive ISO range, fast shooting speed, and 1080p video capabilities. It is over 30% faster than its predecessor thanks to a new image processing engine, EXPEED 4. The 51-point AF system with 3D Color Matrix metering provides fast focusing and accurate exposure, tones, and color rendering. Boost your ISO range all the way up to 409,600, ensuring coverage in even the trickiest lighting situations. Enjoy increased security and versatility with dual card slots – one for CF and one for XQD. An anti-slip pattern has been added to the joystick for better, more tactile control, while a larger overall card slot cover gives you more grip space for better ergonomics. Illuminated buttons have been maintained, as well as weather sealing. The entire shutter and mirror mechanism has been adjusted for better performance and higher visibility when shooting at fast, continuous speeds. This camera delivers incredibly faithful tones with smooth gradation for both stills and video. The processor suppresses moiré, false colors, and "jaggies". Nikon focused their noise reduction technology specifically on improving video in low light. With its 11 FPS shooting speeds, wide exposure latitude, and rugged build, the Nikon D4s Digital SLR Camera is ideal for sports and wildlife.
