Image Sensor Cleaning

D3S

Dust that reaches the image sensor can result in unattractive spots on your images. After relentless testing, Nikon engineers have designed Nikon’s first Image Sensor Cleaning function for an FX-format flagship camera. The unit generates vibrations at four specific frequencies to optimize dust removal. This function can be set to operate manually, or to run automatically when the camera is turned on and off.

Moreover, Nikon takes extra measures to prevent dust with its Integrated Dust Reduction System. Numerous parts are built to generate minimal dust, while other components have been designed to either repel dust or prevent it from reaching the Optical Low Pass Filter and sensor.

Nikon Integrated Dust Reduction System

[Minimal dust is generated]
  • Drive mechanisms such as shutter unit are designed to minimize dust generation
  • Certain parts are operated prior to body assembly so as not to disperse dust after mounting within the camera
[Minimal dust adheres to OLPF]
  • OLPF has an antistatic design to prevent dust sticking
  • Dust absorption mechanism around OLPF
  • Rear side of the image sensor is sealed to prevent dust
[Dust is minimally reflected in images]
  • Sufficient distance between OLPF and the CMOS image sensor prevents dust being photographed
[Reducing the effects of dust and foreign matter]
  • Image Dust Off function of the optional photo editing software Capture NX 2 effectively eliminates the effect caused by dust when using a computer (for RAW data only)
  • Auto Retouch Brush of the optional photo editing software Capture NX 2 removes dust photographed on an image

Viewfinder

Approx. 100% frame coverage

The large prisms of the D3S and D3X give you the FX-format visual advantage when you shoot. Both have approx. 100% frame coverage, so what you see through the viewfinder is a precise perspective of the visual information that the image sensor will detect when you press the shutter release button. Not only is the viewfinder image bright — the screen is also carefully designed for you to sense focus intuitively, be it manual or autofocus. It ensures that a photographer can view everything, including shooting information, without moving his or her eye away. The viewfinder also features an 18mm (-1.0m-1) eyepoint, so photographers who wear glasses can concentrate on capturing the right moment.

Durability — Designed to work in the toughest conditions

Magnesium Alloy Body

Nikon’s rugged, durable and precise magnesium alloy construction protects the incomparable technologies of the D3S and D3X and their ability to perform in demanding real-world conditions. An amazingly strong-yet-lightweight magnesium alloy is used for the body, exterior cover, chassis and mirror box to assure superb, reliable performance and longer life.

Countermeasures against dust, moisture and electromagnetic interference

The D3S and D3X go the extra mile to protect against invasive moisture, dust and even electromagnetic interference. A comprehensive series of O-rings and other specialized seals, combined with additional Nikon engineering, keeps you shooting when lesser cameras would fail.

Comprehensive sealing (D3S)

Stainless-steel lens mount (D3S)

The material of the lens mount of the D3S has been changed from the plated brass of the D3 to SUS (stainless steel) to realize improved ruggedness and durability. Advanced specifications that assume severe conditions such as frequent changes of lenses and rough handling during shooting achieve the high reliability professionals demand.

Shutter Unit

Durable Shutter Unit

Nikon’s proprietary shutter mechanism achieves unprecedented durability. For the reliability professionals demand, the shutter of the D3S and D3X has been tested for 300,000 cycles. And to ensure rigorous real-world conditions, this type of testing is always performed on fully assembled cameras.

Self-Diagnostic Shutter Monitor

Shutter speeds range from 1/8,000 to 30 s, with an internal mechanism that automatically monitors and corrects possible variances between the designated shutter speed and the actual shutter timing over the shutter mechanism’s life span.

Mirror Balancer

A sophisticated mirror balance mechanism reduces the time required to lower the mirror. In addition to minimizing mirror bounce, the mirror balancer extends viewing time, which allows more time for AF operation — this is one reason the D3S and D3X can offer autofocus and Focus Tracking even at high-speed continuous shooting.

Twin CF card slots

You can use two CF cards simultaneously for a number of functions: recording two full CF cards of data; recording the same data simultaneously onto two cards for backup protection; transferring data from one card to another; or for recording RAW and JPEG simultaneously onto separate cards. With the D3S, you can also designate the card slot to record D-Movie capture. Just confirm the available time for D-Movie recording for each card slot through the menu. By selecting the card slot with the most space, you can avoid D-Movie recording ending unexpectedly due to a shortage of card space. Data capacity this large and versatile allows photographers to concentrate on shooting without worrying about their storage space, further aiding their workflow efficiency.

Long Battery Life

The D3S and D3X use the same EN-EL4a (provided) or EN-EL4 rechargeable batteries whose capacity and reliability have been field-proven over the years. What’s more, because the power consumption and power management systems of the D3S and D3X have been engineered for greater operating efficiency, professionals can expect exceptional battery life: up to approx. 4,200 frames per charge with the D3S* and as much as 4,400 frames per charge with the D3X*.
