- Principle of electric release:
Most of the
cameras have a shooting sequence as this:
release button, there are three connections: com,
- when pressing half way the release
button, com and
are connected and the camera memorize the distance.
- when pressing fully, obt is connected,
and the camera sets the lens, and triggers the shutter.
So, it is necessary
, in each camera, to identify these three connections near
the release button, and then to connect and install a plug
that can be connected from outside..
two wires only are sufficient because it is possible
to connect, after this plug, the map and obt functions.
When releasing, the contact will be done with com, which
will not impede the camera first to set the distance, the
exposure control, and then to shot.
Once the external
plug removed, the camera is working as usual.
Olivier Humez set the wire com
at the center of the plug. Being symmetrical, the plug doesn't
need an index.

The female plug is set inside the camera, and the male plug
