The Nikon D4S DSLR Camera is equipped with a full-frame, FX-format 16.2MP CMOS sensor and an EXPEED 4 image processor, which allows it to capture high-resolution still images and full HD 1080p videos with exceptional picture clarity, quality, and sensitivity while maintaining low noise.

The combination of these two technologies results in remarkable image quality, which is characterized by smooth tonal gradations, bright, but accurate color reproduction, as well as an expanded dynamic range, among other characteristics.

Shooting in a wide range of lighting settings is made easier with the D4S’s large native sensitivity range, which extends from ISO 100 to 25600 and can be further expanded to an equivalent ISO 409600 for working in harsh lighting circumstances.

Furthermore, the EXPEED 4’s processing capability allows for a full-resolution continuous shooting rate of 11 frames per second for up to 200 frames with sustained auto-exposure and focusing.

In addition to the similarly enhanced 51-point autofocus system, which can be adjusted to use five AF points as a single focusing point in the Group Area AF mode for improved initial subject identification, this camera also features a 61-point hybrid autofocus system.

Aside from helping to improve the focusing skills of the D4S, the 3D Color Matrix Metering III technology, which works in conjunction with the 91,000-pixel RGB sensor, also helps to deliver precise exposure metering for a wide range of objects and lighting circumstances.

In addition to supporting a rapid, time-sensitive workflow, this camera utilizes a number of tactics that aid in the offloading and transmission of files as quickly and efficiently as possible.

In addition, support for a 1000 Base-T (Gigabit) wired LAN connection is provided, and file recording is supported in a 12-bit RAW SIZE S file size to aid in the expediting of post-production workflows.

It is possible to record uncompressed movie files while simultaneously recording to memory cards and see the footage in real-time when using optional external recorders while recording movies or time-lapse pictures.

Image processing is handled by a 16.2MP FX-format CMOS sensor and an EXPEED 4 image processor.

Its 16.2-megapixel full-frame (FX) CMOS sensor and its EXPEED 4 image processor work together to produce images with the outstanding overall quality and outstanding detail as well as dynamic range, color accuracy, and low-light sensitivity up to a native ISO 25600, which can be further increased to an incredible ISO 409600.

Furthermore, the EXPEED 4 processor contributes to the camera’s overall performance, which includes a full-resolution JPEG continuous shooting rate of 11 frames per second for up to 200 photos with sustained autofocus and auto-exposure metering. At 11 frames per second, up to 104 photos can be captured when working in the 14-bit RAW shooting mode.

Full-HD video recording is available.

Aside from increased processing power, the ability to capture full HD 1080p video at frame rates of up to 60 frames per second is another advantage of the upgrade. Multi-area modes, which are available in FX, DX, and 2.7x Crop settings, allow you to reduce your effective field of vision when recording, as well as while shooting.

This provides you with greater freedom during shooting. Even when working in manual exposure mode, you may use the ISO Auto Control feature, which allows you to alter audio settings in real-time. This feature includes better wind noise reduction, as well as customizable frequency ranges such as Wide

Range and Voice Range.

It is possible to record to an optional external recorder in order to obtain an uncompressed video signal through the HDMI connector. When recording externally, it is also possible to use the camera’s LCD panel for live view monitoring.

Additionally, it is able to record to both memory cards and an external recording device at the same time, allowing for immediate backup and duplication of information. During video recording, still photos up to 2MP can be captured at the same time as the video.

Sensor with 51 points of advanced multi-CAM 3500FX AF

The D4S’s extraordinary image capabilities are supported by an excellent autofocus system that utilizes up to 51 different points and can be configured to use 9, 21, or all 51 points, depending on the circumstances.

3D Tracking, which is a component of the sophisticated Scene Recognition System, is especially useful for maintaining focus on moving things while shooting at high continuous shooting rates, resulting in higher accuracy and precision.

If you want even faster initial focusing and subject identification, you may group five autofocus sensors together and utilize them as a single focus point by utilizing the Group Area AF mode. Single-point AF, Dynamic-area AF (with 9, 21, or 51 points configurable), 3D-tracking (with all 51 points), and Auto-area AF are all options.

When working in live view, whether for still or video photography, a contrast-based AF system is used to acquire focus precisely. This system can also operate in continuous, full-time servo mode, which is more suitable for dealing with subjects that are in motion.

When employing the contrast-detection focusing method, four different AF-area options are available: face-priority AF, wide-area AF, normal-area AF, and subject-tracking AF. Face-priority AF is the default setting.

In order to quickly determine an accurate exposure and white balance setting for the scene at hand, the intelligent Scene Recognition System with 3D Color Matrix Metering III makes use of a 91,000-pixel RGB sensor to evaluate and analyze all aspects within a scene, including brightness, contrast, subject distance, and the scene colors.

This allows the camera to render the scene at hand in the best possible way. During the data collection process, the information obtained is compared against onboard reference photographs to guarantee consistency from image to image in terms of exposure, white balance, i-TTL flash settings, and subject-tracking autofocus performance.

Specifications of the camera’s design

  • A 3.2-inch 921k-dot LCD monitor is offered as a big way of viewing live views, playing back images, and navigating through menus and options. Aside from that, color settings on the display may be manually modified to fit the color balance of external monitors or other color balancing needs.
  • Two card slots, one for CompactFlash and the other for XQD cards, are provided to expand file-saving capabilities by allowing for either overflow recording or in-camera file duplication. Aside from that, optional HDMI-connected external recorders may be used to capture uncompressed video and time-lapse sequences, among other things.
  • The ergonomic grip and overall form factor are designed to make it easier to handle for extended periods of time. Anti-slip, textured joysticks and easily accessible card-slot covers add to the convenience of handling for extended periods of time. Aside from that, most of the rear buttons on the back of the camera are lighted to provide improved vision while operating in low-light circumstances, which is very useful.
  • The camera’s sturdy magnesium alloy body is equipped with strong weather sealing to keep dust, moisture, and electromagnetic interference out.
  • In conjunction with an improved mirror balancer, which provides greater vision and reduces mirror shaking when operating in high-speed continuous shooting modes, a very robust shutter with 400,000 cycles of testing has been developed and tested.
  • The bundled EN-EL18a rechargeable lithium-ion battery pack has a capacity of about 3,020 shots per charge and may be recharged many times (in single-frame mode, based on CIPA standards).

Transferring images and connecting to the internet

  • High-speed, smooth transmission of still pictures and video data is made possible by the integrated wired LAN function, which adheres to the 1000 Base-T (Gigabit) standard, allowing the whole post-production workflow to be accelerated.
  • WT-5A and WT-4A Wireless Transmitters are optionally available for wireless file sharing with the D4S, which is compatible with both models.

Additional Camera Functions

  • An improved interval timer allows for the recording of up to 9,999 frames with intervals as long as one week using a single battery. Records can be made to memory cards, an optional external recorder, or both types of media at the same time, depending on the camera model.
  • Furthermore, exposure smoothing and flicker reduction are beneficial for time-lapse playback, resulting in more seamless and dynamically generated videos.
  • RAW (NEF) files can be recorded as lossless compressed or compressed at either 12 or 14-bit depth, depending on the camera. Aside from that, data can be stored in the RAW SIZE S format, which can aid to accelerate a photographer’s workflow while still keeping the picture quality-related assets associated with the RAW format.
  • When working in live view, the following picture area modes are available: FX, DX, and 2.7x.
  • When shooting via the viewfinder, a custom option allows you to toggle Face Detection on or off based on the exposure metering bias that you want to use for your shots.
  • Auto ISO sensitivity adjustment allows you to pick a minimum shutter speed below which camera shake may be managed, and then the camera will automatically set the ISO value to the highest possible setting in order to portray the image as accurately as possible. It is also possible to select a maximum sensitivity level in order to keep overall noise levels consistent.
  • Spot White Balance control for live view shooting makes it as simple as pointing to the part of the frame that should be white to adjust the white balance for the entire frame. Additionally, 1-6 pre-set white balance settings may be saved to make transitioning between different light sources faster and more convenient.
  • Picture Control modes, which include Landscape, Monochrome, Neutral, Portrait, Standard, Vivid, and user-customizable settings, allow you to apply predefined looks to imagery captured in-camera. Picture Control modes include Landscape, Monochrome, Neutral, Portrait, Standard, Vivid, and user-customizable settings.
