four years later and reading this post . I mostly used Nikon but after having my back up d90 stolen by a man off of kijji who came to buy another camera and picked up both and left ...I bought the 30d as a backup I just read eos of this age is too old to high speed sync ..actually it is very easy to high speed sync on it
all of canons hss and off market do work on it as HSS...in case anyone is looking through threads and end up here like I did looking for an answer to the question
Image I did today with the canon 30d and an after market HSS (tr988) that I can actually use on both my nikons and canons
I had to change no in camera setting ( unlike my d600 and other nikons) it does manual HSS or ttl hss
