I did a quick search to see if they were compatible, but couldn't find anything specific.
At any rate, came across a Vivitar 285, and couldn't pass it up for the price. I was initially thinking I could mount it on a tripod, and use it as part of a pair to shoot portraits. Once I got my hands on it, and saw how much light it puts out, I started to wonder if I could use it mounted directly on my camera for low light indoor shots.
The Vivitar does not specify if it is an 'HV' or not, so I'm not sure if it's a plain 285 or a 285 HV, OR if there really is a difference.
I did come across a thread on another forum that listed the compatibility of Vivitar flashes with Canons, but for the 285 it only listed a questionable compatibility. There's a company that sales a mount for dual 285s w/ power supply and wireless flash triggers, and this website states that the 285's could possibly 'fry' a DSLR.
Anyhoo, anyone use a 285 on your Canon Xti? I'm going to eventually buy a 580ex flash, but that will have to wait until I upgrade to a new lense. I can't wait to get my hands on a 580 to try one of Gary Fong's diffusers.
Thanks for any help.
