Hello,


I would like to get the flash off the camera to expand my opportunities. I have never used off camera flash before and I would like to know how wellthe Canon equipment works. I have read that the Canon Transmitter works with inferred light signals and understand that they are somewhat limited and can be "confused" sometimes and that there distance is limited.


Also,will the TTL system still work?


I have a 30D and 1 580 EX version 1 and will possibly add another flash.



Thanks in advance for any advice,


Tank
