Reliability

“The camera worked impeccably despite the considerable punishment I put it through. From the blistering sands of the Thar Desert to the jarring ride atop camels and over the potholed back roads of India's mountains, the Q0810 never let me down.”

Shutter unit

Durable shutter unit

To achieve reliable real-world durability, Nikon tested the shutter unit through 150,000 cycles on a fully assembled D300S camera, in demanding test environment. It's a trial that ensures a long service life and, above all, the certainty that the shutter will always click, together with the confidence that inspires.

Body

Robust, magnesium alloy body

Ruggedly constructed for long years of service in the demanding real-world shooting situations faced by professionals, the D300S employs a strong yet lightweight magnesium alloy for its exterior cover, chassis and mirror box, as well as for the cover of the optional Multi-Power Battery Pack MB-D10.

The D300S also offers protection against invasive moisture and dust, securely sealing major seams and joints.

Dual card slots

Versatile dual card slots - CF and SD memory cards

The D300S provides dual card slots for different card types, enabling you to use both CompactFlash* and SD memory cards and to designate the primary recording slot. For the secondary slot, you can select from three recording methods: "Overflow" recording lets you use the memory capacity of the secondary card when the primary card is full, automatically; "Backup" recording stores the same images on both cards; and “RAW primary, JPEG secondary” recording lets you record RAW data and JPEG data separately to each card. Furthermore, when shooting D-Movie clips, it allows you to select the slot containing the card with the most available capacity — a significant benefit. You can also copy images between the two memory cards.

* Type Ι compatible only.

Memory card capacity

The following table shows the approximate number of pictures that can be stored on a 4 GB SanDisk Extreme IV (SDCFX4) CF card at different image quality and size settings.

1.All figures are approximate. File size varies with scene recorded.

2.Maximum number of exposures that can be stored in memory buffer at ISO 200. Drops if optimal quality is selected for JPEG compression, ISO sensitivity is set to Hi 0.3 or higher, High ISO NR is on when auto ISO sensitivity control is on or ISO sensitivity is set to 800 or higher, or long exposure noise reduction, Active D-lighting, or image authentication is on.

3.Maximum frame rate when recording 14-bit NEF (RAW) images is 2.5 fps.

4.Figures assume JPEG compression is set to Size priority. Selecting optimal quality increases the file size of JPEG images; number of images and buffer capacity drop accordingly.

Approved memory cards

• Type I CompactFlash memory cards

• SD memory cards*

* All cards listed can be used, regardless of speed.

† If card will be used with card reader or other device, check that device supports 2 GB cards.

‡ SDHC compliant. If card will be used with card reader or other device, check that device supports SDHC.

Sensor cleaning

Nikon's Integrated Dust Reduction System

Any dust that reaches the image sensor results in unattractive spots on your images. To prevent this, the D300S employs Nikon's Integrated Dust Reduction System, which includes a self-cleaning sensor unit with four different resonance frequencies to vibrate the optical low-pass filter and shake dust away from the sensor. This function can be set to operate automatically when the camera is turned on or off, or to manual.

Low-power consumption

Long-life battery

Battery life is a constant concern of photographers on location shootings, and in response to this, the D300S provides excellent power management. The Rechargeable Li-ion Battery EN-EL3e (supplied) allows you to shoot up to approx. 950 shots*1 (3,000 shots*2) per charge. If you attach the optional Multi-Power Battery Pack MB-D10 using Rechargeable Li-ion Battery EN-EL4a, that number is boosted up to approx. 2,950 shots*1 (8,900 shots*2), far beyond anything else in its class.

*1 Based on CIPA Standards.

*2 Achieved under following test conditions: image quality set to JPEG basic, image size set to M (medium), shutter speed 1/250 s, shutter-release button pressed halfway for three seconds and focus cycled from infinity to minimum range three times; six shots then taken in succession and monitor turned on for five seconds and then turned off; cycle repeated once exposure meters turned off.
