I had a pair of them that worked like champs. It's a shame that the new Canon cameras don't support it. So, yeah I'd say other than voltage issues both of those flash units are good. I still don't know whether this really matters. It is hard to imagine the firing circuit in the 10D would be designed to be hurt by this, since among "low voltage" flashes this is not an unreasonable voltage.
Canon has no warning in their manual except that a high voltage flash "might not fire". There is no mention of damage, etc, so what gives I wonder? I imagine they have some kind of open collector drive or something. Surely it's not really a "6 V transistor". Egad, if so, what a crappy design. Maybe so. Have fun, Andy some cameras, some l enses, and still a lot of things to learn I design electronics, and it just seems odd that a camera designer would design a hotshoe interface that was mechanically compatible with most anything, but that would also get damaged by most anything.
It might be true, but if so it's a booby trap design and doesn't serve the customer very well. If the camera will be damaged by 12V, then why doesn't the Canon documentation say more than "might not fire"? I mean, yeah if it gets blown out For the record they told me that the trigger voltage must be limted to 6V.
I accept this as definitive, but I'm flabbergasted nonetheless. Why didn't they create a different hot shoe so that people can't stick a garden variety "dangerous" 12V flash on it?
They recommend Canon Speedlites. Of course we know that there are lots of non-Canon flash units out there. Some of them are compatible and some are not. Canon is not going to promote how you can use a non-Canon flash. They really want you to buy Canon. So, by restricting the compatibility on the camera end by having a low voltage spec , they will scare half of the consumers into Canon-only, and they will intice the other half by other methods like fancy features.
If a user puts on an old Vivitar flash like mine, volts and if it burns up something on the Canon camera, then it is no sweat off Canon's brow.
They will probably score a hefty repair fee and then score the price of a Canon Speedlite. They are in business to make money. So what. They also need to serve the customer. So rather than just saying something about the DANGER in their own documentation, they are relying on a largely incompetent sales force spread throughout the chain camera stores of the world to convey this critical information??
If they do it on purpose, then they are unethical. Yes I understand they want me to buy Canon. So what? Any company that views customer damage, to which they purposely contribute in terms of misleading the customer, as a source of income is unethical. Van Abbott. Red Viper. Save 30 bucks.
