Remote shutter release for canon

[HDNitehawk]

I guess wireless is the best way to go?

I do not think so unless you are trying to get in the shot or something similar. From your post I took it that is not what you are doing.

On the 5D II the sensor was in front of the camera, to get Canon's version to work you had to reach around or be in front of the camera.
Anyway I was never impressed, so I changed to Canon's wired release.
But, that was not the best way either.

When you are doing landscape shots you have to watch how your cord lays. The Cord itself can set up a vibration from your hands when a camera is in a tripod.

Touching the shutter does the same.

So the best way for the picture is mirror up, set a delay. It takes several seconds if the camera is on a solid tripod for the vibration to stop after touching the shutter. So click the shutter and get your hands off, and give the camera the time to settle out before the timer kicks the shutter.
