Worked right out of the box, no syncing required.
I Use the RC-5 for self included photos, vacation shots, parties and family reunions.
The RC-5 Gives that steady shot necessary for that all imoprtant shot when mounted on your tripod.(yes even with that fast shutter speed you can loose a shot) with the slighest movement,especially when you use that powerful zoom it is easy to blur a shot.
For the price you will never regret using this great product by Canon
I used my wireless remote for a family photo shoot that I was in and it was Wonderful. I was able to set everything up and get everyone in place and then get myself in the picture and then use the remote. It was very easy to use.
