fire position for long, timed exposures. Plugs into the 10-pin
socket on the front of the camera.
MC-35 GPS Cord. This short cable plugs into the Nikon 10-
pin connector at the camera end and provides an RS-232 type
of connector at the other end, and was designed to be used
with third-party GPS units that have optional cables.
MC-36 Remote Cord. This 2.6' (80cm) cord is a more
complex shutter release for the D300 (plus D1, D2, D3, D200
and current 35mm film bodies, such as the F100, F5, and F6).
Besides operating as a regular release, it can also function as a
timer remote or intervalometer remote. Plugs into the 10-pin
socket on the front of the camera.
ML-2 Modulite Remote Control Set (requires MC-25). This
unit provides remote control at up to 328 feet (100m) using
infrared signals. Multiple units can be daisy-chained together
to trigger the camera from longer distances. Plugs into the 2-
pin socket at the end of an MC-25 (requires line of sight
between the unit plugged into the MC-25 and the control
station).
ML-3 Modulite Remote Control Set. Like the ML-2, the ML-3
provides infrared remote control of a D300, although at a
greatly reduced range (26.2' [8m]).
