Hi, I have a flash that triggers at approximately 12V (measured, not from the specs), and I am wondering whether it is safe to use with the hotshoes of the mentioned EOSes. I have seen contradictory advice in these fora and elsewhere; indeed, some posts say that anything under 250V is fine on the PC connector and on the hotshoe too, others say that this is the case with 20D (and presumably the 30D) only while the 10D syncs safely at 6V and under only, and finally other posts say that the 6V limit is applicable to all the digital EOSes. I have written recently to Canon Canada and they replied quite confidently that the hotshoe trigger voltage limit for both the 10D and the 30D is 10V (this being the first time I hear the 10V variant). In all, I am confused. I am then wondering whether anybody here has any direct experience with all of this. The 12V trigger voltage is very close to the Canon-claimed limit of 10V, so I am tempted to try it out. However, I obviously don't want to fry anything, so if anybody can shed some light (pun not intended) on the matter it would be appreciated. Many thanks in advance.
