Hi all.

I currently have two Cobra Auto210 flash units that I use with my S9600. One for the hotshoe and the other with a slave device.

I'm considering upgrading my camera to either a Canon 1000d or a Nikon d3000. Would the flash voltage be too much for the cameras?

You'd need to measure the trigger voltage of the flash, a quick Google suggests it may be circa 270v, which could damage either of those cameras and would definitely kill the likes of the RF602/PT-04 or YN-04 triggers.

b****r. :(

How would I measure the voltage? Just a multimeter on the contacts and set off the flash?

I suppose I could still use them both as remote flashes.

Do the cameras mentioned have the option to just flash once, or do they do the pre-flashes on all settings? (pre-flash cocks up the remote sensor I have)

If you look at the foot of the flash there is a small connection on the side of the hotshoe, put the meter between that and the centre pin to get the voltage.

With regard to pre-flash (only required for ttl), there are two ways to get around that - invest in one of the optical slaves that will ignore it, or shoot in manual.
