The D300's connections are in two places, either at the front top (remote and flash PC sync) or the left side of the body (from the rear). The remote (which also allows for serial GPS) and flash PC sync terminals are now protected by a rubber cover which is itself attached to the strap eyelet. On the side are the largest group of connectors, from top to bottom; Video out (composite), HDMI (digital video out HD/SD), DC-IN and USB 2.0. The biggest story here must be HDMI output, from the camera menu you can select five different output options; Auto, 480p, 576p, 720p or 1080i. For an example and video clip of HDMI output see this page of this review.

Camera Base / Tripod Mount

The bottom of the D300 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.

You can also see the connectors for the optional MB-D10 grip (see previous page). These would normally have rubber covers over them.

Pop-Up Flash

The D300'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 D300 has a standard (ISO 518) accessory shoe which is compatible with third party flash systems for flash sync and more advanced i-TTL with the SB-800, SB-600 or SB-400. Non-TTL Auto available with the 80DX, 28DX, 28, 27, and 22s.

Lens Mount / Sensor

Below on the left you can see the D300'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.

Self-cleaning sensor unit

We knew Nikon couldn't wait too long before implementing some kind of automatic sensor cleaning system, and so the D300 becomes the first Nikon with such a feature. 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.
