Only the Nikon mount ones can be triggered using radio triggers, like Pocket Wizards, Cactus, Phottis. - This is enabled via a firmware update.
I almost bought the Nikon Mount one just to use as an off camera flash. Until I discovered the great value of the YongNuo 460 II
ya i heard about it. nissin 622 cannot be trigger by wireless triggers.. i was a bit surprised though as i tot as long u buy a set of wireless triggers with transmitter and receiver, everything will be okie.
have to wait for the firmware update.. they updated the Nikon Nissin Di622.. but not for Canon yet
