The Nikon D4S DSLR Camera features a full-frame, FX-format 16.2MP CMOS sensor and EXPEED 4 image processor to produce high-resolution still imagery and full HD 1080p movies with notable image detail, quality, and sensitivity. The combination of these two technologies affords exceptional image quality, marked by smooth tonal gradations and vivid, yet accurate, color reproduction as well as an expansive dynamic range. Championing working in a wide variety of lighting conditions, the D4S also features a broad native sensitivity range, from ISO 100-25600, that is further expandable to an equivalent ISO 409600 to benefit working in difficult lighting conditions. Furthermore, the processing power of the EXPEED 4 also affords a full-resolution continuous shooting rate of 11 fps for up to 200 frames with maintained auto-exposure and autofocus. Aiding the imaging prowess of this camera is an equally refined 51-point autofocus system, which can be configured to utilize five AF points as a single focusing point in the Group Area AF setting for heightened initial subject recognition. The 3D Color Matrix Metering III system, along with the 91,000-pixel RGB sensor, also benefits the focusing abilities of the D4S as well as provides accurate exposure metering to suit a vast array of subjects and lighting conditions. Complementing a fast, time-sensitive workflow, this camera also employs numerous strategies designed to benefit fast offloading and transferring of files. Support is available for a 1000 Base-T (Gigabit) wired LAN connection and file recording is possible in a 12-bit RAW SIZE S file size to help expedite post-production. When recording movies or time lapse imagery, optional external recorders can be used to record uncompressed movie files, with simultaneous recording to memory cards and live view monitoring possible. 16.2MP FX-Format CMOS Sensor and EXPEED 4 Image Processor The 16.2 megapixel full-frame (FX) CMOS sensor and EXPEED 4 image processor work in tandem to deliver high overall image quality with notable detail, dynamic range, color accuracy, and low-light sensitivity to a native ISO 25600, which is further expandable to an exceptional ISO 409600. Furthermore, the EXPEED 4 processor also contributes to a wealth of speed throughout the camera, including a full-resolution JPEG continuous shooting rate of 11 fps for up to 200 shots with maintained autofocus and auto-exposure metering. When working in the 14-bit RAW shooting mode, up to 104 shots can be recorded at 11 fps. Full HD Movie Recording Also benefitting from the enhanced processing power is the ability to records full HD 1080p video at frame rates up to 60 fps. Multi-area modes enables you to narrow your effective field of view during recording, too, in FX, DX, and 2.7x Crop settings to offer more versatility during shooting. ISO Auto Control is available when working in manual exposure mode as well as real-time adjustable audio settings with enhanced wind noise reduction and selectable frequency ranges such as Wide Range and Voice Range. Recording to an optional external recorder is possible in order to gain an uncompressed video signal via the HDMI port and, when recording externally, use of the camera's LCD monitor for live view monitoring is possible. Additionally, simultaneous recording to both memory cards and an external recording device is also possible for instant backing up and duplicating of files. 2MP still images can also be recorded simultaneously during video recording. 51-Point Advanced Multi-CAM 3500FX AF Sensor Supporting the exceptional imaging capabilities of the D4S is an apt autofocus system that employs up to 51 distinct points, with options available to use 9, 21, or all 51 points depending on the situation. 3D Tracking, as part of the intelligent Scene Recognition System, also works to benefit maintained focusing on moving subjects for greater accuracy when shooting at high continuous shooting speeds.
