All of the connectors are located on the left side of the body (from the rear) protected by rubber covers. At the top we have USB 2.0 (Hi-Speed), DC-IN connector and A/V out. At the bottom behind a separate cover is the connector for the new MC-DC2 remote cord or GP-1 GPS unit.
Camera Base / Tripod Mount
Nothing shocking, a fairly standard camera base with a metal tripod mount located in line with the center of the lens and focal plane. The D90 doesn't have a rubber foot covering the rest of the base area.
The D90 has an electronic-release pop-up flash which will either raise automatically (in Auto or one of the Scene modes depending on the flash mode) or manually by pressing the flash button. This button also doubles as the flash mode and flash compensation button, by holding it and turning the main or sub command dial. The flash has a guide number of 12 (m at ISO 100) - roughly the same as the D80 - and raises approximately 50 mm above the top of the lens. The built-in flash can also act as a commander in a wireless flash setup.
Lens Mount / Sensor
Below on the left you can see the D90'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).
Self-cleaning sensor unit
The D90 has the same automatic sensor cleaning system as found on 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.
