5d Miii sync speed

[kanuski]

The sync speed for a 5D Mark III is listed as 1/200 but it is not working for me. At 1/200 I am getting shadow from one of the curtains. Any ideas about why this could be happening? Could it be camera settings, firmware, gremlins?

Are you using aftermarket triggers? I've seen people have issues at times with certain 3rd party triggers. Usually going down to 1/160th is enough.

Do you have silent shooting enabled?

Thanks, You might be on to something. I thought it still happened with on camera flash but I was wrong. With the flash on the camera the flash works at 1/200. When I use the YN 603 triggers I can only go to 1/160.
