Thanks for your help and the links, I have not actually bought my flash yet I have been looking
however with not knowing to much about them I don't want to buy the wrong one, I have been looking
at the yonguno 565 ex but not sure if it will work on both the 350d and the 1100d I have looked on the
web site and it just puts a ? next to the 350d and says there has been no feed back re- the 350d so they
do not no if or not it would work. I have wrote an email to them and am waiting now for a reply then if it
will work I can then go ahead and buy the flash and the triggers together.
Thanks Geoff Merry Christmas to all
