Would a Vivitar 728 flash work with a Canon XTI with all its functions?

I've been reading around and it seems that a vivitar 728 would work with an xti but not the autofocus and other functions. could anyone tell me if this is true, and if it is, is their anyway to adjust it?Would a Vivitar 728 flash work with a Canon XTI with all its functions?
Technically, yes, the flash will fire. That's about the only ';function'; that will work on the flash. Everything else will be pretty much full manual. You'll lose the E-TTL flash exposure system, which can calculate flash power based on distance (E-TTL 2 does this), so you'll be manually adjusting power on the flash- a lot of your photos will be guesswork.





Also, if something goes wrong and your camera gets fried, Canon will point at Vivitar and claim their hardware caused it and may refuse to service your camera as a result. Is there something pushing you towards the 728 that you wouldn't get with the 430EX or 580 EX II? Like the previous poster said, it would be more advisable to have a system you know is compatible with each other.Would a Vivitar 728 flash work with a Canon XTI with all its functions?
IMO you will be happier with the Canon flash designed for your camera. Buy the top of the line they offer for your XTi and you'll never be disappointed. In the 36 years I've enjoyed photography I've found its better to have a feature and not need it than to need it and not have it. You should also buy the off-camera flash bracket Canon offers and the cables (if any) needed to connect the flash to the camera. You will now have a completely compatible system which you're unlikely to ever outgrow.
