The D3000 only has two connections - video out, and mini USB. As we would expect of an entry-level DSLR the D3000 lacks a PC socket for an external flash, and there is no HDMI port either, although the omission of a video mode makes HDMI connectivity less of a priority than it might otherwise have been.
As usual, the ports are concealed behind a rubber cover that fits flush to the body when the ports are not in use.

Camera Base / Tripod Mount

A metal tripod socket is fitted on the bottom of the D3000, towards the aft of the body. It is positioned centrally on the lens axis. The base of the camera is ridged for increased grip on a tripod plate, but not rubberized.


The D5000 has an electronic-release pop-up flash which raises either automatically (in Auto or one of the relevant Scene modes) or manually by pressing the flash button. This button also doubles as the flash mode interface, and pressing it whilst moving the control dial scrolls through the available flash modes. Unlike the D90 and above, the D3000 cannot act as a controller for Nikon's wireless 'Creative Lighting System' flash setup.

Lens Mount / Sensor

Below on the left you can see the D3000'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. Like it's predecessor the D60, and the D5000 higher up the range, there is no AF motor built into the body of the D3000, meaning only lenses with autofocus motors will focus automatically. All three major third-party lens makers (Sigma, Tamron and Tokina), now sell lenses with built-in AF motors for Nikon, but Nikon users with large collections of 'legacy' AF-D and earlier AF lenses will need to focus manually or save up for a D90.

Self-cleaning sensor unit and airflow system

The D3000 has a self-cleaning sensor unit which works in the same way as the system built into the D5000 and D90. In essence, piezoelectric elements vibrate the anti-aliasing filter that covers the sensor at an extremely high frequency, thus theoretically dislodging any dust and dirt. By default, sensor cleaning is schedules for startup/shutdown and it can also be activated on demand.

The D3000 has another weapon in its anti-dust armory in the form of the airflow system, first seen in the D60. Airflow uses the changes in air pressure and circulation when the mirror is moved to direct loose dust particles in the mirror box onto a sticky pad. The pad is buried in the base of the lens throat, covered by the perforated grill shown here at lower right.
