Compact Flash Compartment

The D300S has gained the card door from the D700 - losing the reassuringly secure latched version of the D300. The new slide-and-open version features a similar level of foam sealing around the card slots themselves. The immediately noticeable change is that the door now conceals two card slots -

Battery Compartment

The battery compartment is located in the base of the hand grip. The compartment door is opened by pulling on a small lever, inside the battery holds itself part of the way in without dropping and without the use of a catch.


The D300S gains a microphone connector behind the large rubber ports cover on its left flank. Also here are a composite A/V connector, HDMI port, DC power in and USB connector. The HDMI output can be defined in the camera's Setup menu (With options of Auto, 480p, 576p, 720p or 1080i).

The PC sync flash socket and remote/GPS connectors are on the front left corner of the camera, protected behind rubber covers that are permanently attached to the camera (so won't get lost like screw-in PC sync caps can). (PC sync images are of D300)

Camera Base / Tripod Mount

The bottom of the D300S is a simple enough affair with the metal tripod mount located in line with the center of the lens and the imaging focal plane. I'm also a big fan of the large rubber foot which covers two thirds of the base.

Pop-Up Flash

The D300S's pop-up flash is released manually by pressing a small button on the left side just below the flash. The long arm raises the flash unit a respectable distance above the top of the lens (useful for lens hoods and reducing red-eye). Just below the release button is another button which changes flash mode and flash exposure compensation control button. Hold the button and turn the main command dial (rear) to change flash mode, sub-command dial to change flash exposure compensation (-3.0 to +1.0 EV).

Flash Hot-shoe

The D300S carries-over its predecessor's (ISO 518) accessory shoe which is compatible with Nikon's i-TTL system with the SB-900, SB-800 SB-600 or SB-400. Non-TTL Auto is also available with the older Nikon Speedlights and sync is available with non-Nikon-specific third-party flashguns.

Lens Mount / Sensor

Below on the left you can see the D300S's lens mount with the mirror down, on the right with mirror up and shutter open (exposing the sensor). Lenses are inserted twisted clockwise and lock in place with an anticlockwise turn. This is a standard Nikon F lens mount and can use almost the complete range of Nikkor F lenses (although some features are only available with newer type G or type D lenses). As noted in our introduction the D300 also supports the aperture ring found on old AI lenses. (Images of D300)

Self-cleaning sensor unit

The Nikon D300S has the same self-cleaning sensor as the D300. It works in the same manner as other implementations, piezoelectric elements vibrate a cover filter which should in theory remove any light dust particles attached to it. In use, when we found a dust spot that started to appear at small apertures, it was removed with a single activation of the 'Clean image sensor' option from the Setup menu.
