It's nice to see that Nikon reflect the shape of the normal (landscape) grip in the vertical (portrait) grip, it's very comfortable to use and almost seamless to switch from one to the other. The base of the camera has a soft rubber foot made from similar material as the grip. The metal tripod mount is located in line with the center of the lens and the focal plane. The connector you can see to the left is for the WT-1/2 wireless transmitter.
The D2X has a standard (ISO 518) accessory shoe which is compatible with third party flash systems for flash sync and more advanced i-TTL or D-TTL flash with Nikon Speedlights SB-800, SB-600, 80DX, 28DX, 50DX, 27, 23, 22s and 29s. Note that the 'flash ready' icon on the viewfinder status LCD will only light when using one of the Nikon SB series Speedlights listed above.
Lens Mount / Sensor
Below on the left you can see the D2X'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. The manual notes that "Nikon recommends
using a type G or type D lens to take full advantage of the features the
camera offers." In addition of course the new and expanding range
of Nikkor DX lenses are designed specifically for Nikon digital SLR's. The D2X
also has the ability to use older lenses which do not communicate their
type, aperture or focal length back to the camera, this information can
be set manually via the camera menu.
