Thanks, tried that link earlier when searching the web on the PC but it does not seem to load. Not sure if it is a issue here or with the site.The 622 manual is here http://www.hkyongnuo.com/e-detaily.php?ID=339
Thanks, will have a read on that site.The best resource for the YN622s is known as the TOYUG but I don't know it's Canon largely, there's similarities but major differences too.
