Remote Start Stop for 5D or 7D
As the external shutter remote only control the shutter, the only way to remote the recording is to use a IR remote. But the IR need to be in front of the camera as the sensor is inside the camera hand-grip, not very convenient.
You need to remove the front adhesive layer (there is 2 layers) with a cutter and gently remove the IC board. (Remove the battery before, of course). There is a small switch at the back to delay your remote order. Keep it in “no delay” position to avoid waiting time at each take. I remove the switch cap and use the empty hole for my remote wire.
The Shutter control
The remote is a cheap copy of the canon shutter release but any brand will do. In fact, any push button will do, so a bell push button is fine also
There is 3 wires, but you need only two, you can exchange it, no worries. Usually, remote allow “half push” for focusing, and “full” for the picture. I decided to use the contact for “half”.
You can now put the remote in front of the camera grip and put the camera in the “IR remote” mode. (Very important…)
