I own a Nissin Di622 and currently using this flash optically on my 550D.
I would like to try off-camera using this flash and camera.
Have anyone tried using this flash with a wireless flash trigger ?
I'd watched the RDP's video, and seems it could be fired, but through the 7D I guess.
Pros, please do advice/suggest me on how can I fire my flash wirelessly..
Hope to seek some good advices,
