• Nikon D800 DSLR Camera Nikon FX-Format CMOS Sensor with 36.3 Effective Megapixels The D800 renders levels of texture, nuance and detail to your photography that, until now, have been the exclusive domain of the complicated medium-format system. Define every eyelash, every line in tree bark, and every shimmer of light. Savor the exceptional depth in your still images - with the astounding 36.3 effective megapixels, you can. Enlarge them as big as A1 poster-sized prints (23.4 x 33.1" /59.4 x 84.1cm) at 200 dpi, or crop aggressively to reach the composition you desire, all without sacrificing the detail and tonal range of the original. In order to maintain clean, high-resolution images, 14-bit A/D conversion within the sensor and a high signal-to-noise ratio deliver phenomenal images in a diverse array of situations. The image sensor's incredible potential does not stop with photography, either. For cinematographers ready to put their exceptionally sharp NIKKOR lenses into action, the D800's 36.3 effective megapixel data is efficiently processed for exquisite 1080p broadcast quality video at 30p Standard ISO 100 to ISO 6400 Expandable to ISO 50 to 25,600 Equivalent High-resolution, studio-quality images shouldn't be restricted to the studio. The D800 sets a new benchmark for high resolution D-SLR cameras, with crisp clean images across a wide ISO range. Flexibility like this opens up new imaging opportunities for both still photographers and cinematographers alike during the "magic hour", the time just before dawn or at dusk when available light is often beautiful but scarce. Even at high ISO settings, the camera's intelligent noise reduction systems manage noise without sacrificing fine details, giving the D800 the edge. The difference can even be seen in low-contrast subjects such as hair and grass textures, which are often essential elements of cinema as well as high-resolution portraits and landscape images. High image quality at higher ISOs also means that you can shoot still images handheld more confidently, knowing that fast shutter speeds will reduce blur A Strategic Approach to Turn Light to Your Advantage Combining both high-resolution performance and a wide ISO sensitivity range has finally become a reality. Nikon engineers have developed intelligent new methods to manipulate light transmission to the sensor's photodiodes: from the optical low-pass filter and on-chip gapless micro lenses to the image sensor's internal design, every measure has been taken to maximize and improve light transmission in order to deliver crisp, brilliant images with significantly less noise. All this is possible under a wide variety of lighting conditions, enabling you to get the most out of your NIKKOR lenses Optical Low-Pass Filter Optimized for Sharpness Reducing false color and moire is the main job of the optical low-pass filter located in front of the image sensor. However, this benefit is generally gained with a small sacrifice of sharpness. Moire occurs in scenes containing repetitive details, such as strong vertical lines in architecture. Finding the right balance between benefits and sacrifices is the key to higher image quality, and that is what the D800's optical low-pass filter delivers. As a result, the astounding 36.3 megapixels unleash their potential through an optimized balance between sharpness and effectively prevented moiré and false color. Furthermore, the multi-layer structure of the D800 low-pass filter utilizes layers of antireflective coating that have been optimized for the camera, contributing to sharper and clearer images EXPEED 3 Image Processing Engine: Speed, Versatility, and High Performance High-megapixel still images are detail-rich but data-heavy. With the D800, however, you don't have to sacrifice speed for this privilege. Dedicated to understanding speed and its role in image making, Nikon engineers designed a powerful EXPEED 3 image-processing engine exclusively for digital SLRs. From image processing and card recording to image playback and image transfer, EXPEED 3 manages massive amounts of data at faster speeds than EXPEED 2. Even with specialized processing features like Active D-Lighting and high ISO noise reduction, capture speed is not affected. EXPEED 3 is so powerful that it handles data-intensive tasks such as Full HD video recording at 30p with ease. You'll also notice the difference in your still images and videos through minimized noise and even richer colors and tones. In addition to these fundamental advantages, the D800 reduces the kind of color phase shift that some cameras have difficulty with in similar situations
