syncro cord to eos 350D safe ?

David Altmann , Mar 14, 2007; 01:36 p.m.

is it safe to connect strobes via sync cord to the hotshoe of a eos 350d ? ill use a normal metal hotshoe to sync cord adapter and hensel strobes.

i know canon might say its not say but there are thousands of people doing it anyway. so what do you do ? (no, PW cost more than the camera)

David, you could look in your camera manual and find the maximum flash sync voltage for the 350D and then compare that number to the flash sync voltage in the instruction manual for your strobes. OR, you could simplys connect the strobes with a Wein Safe-Sync Hot Shoe to Hot Shoe High Voltage Sync Regulator (SSHSHS):

oficcially canon says its 6 volts on hotshoes all cameras. sync terminals should be more. my hensel strobes have a sync voltage of 12 volts i think. but i used many cameras including 300d with them and never had a problem. im just asking, becaus i buy think about buying a 350d soon.

The 350D is good for 250V at the hotshoe. It's unlikely to be a problem or require the expensive Wein SafeSync, but you should check the specification for the trigger voltage for your units, or measure it with a high impedance voltmeter.

wow 250 really ? my strobes have a lower sync voltage for sure.

Annoyingly all the manual for the 350D, 400D, 20D, and 30D (and possibly 5D and 1D series) say on the subject is:

"Do not attach a high-voltage flash unit on the camera?s hot shoe. It might not work."

but Chuck Westfall has stated categorically that the 250V limit applies to both hot shoe and PC socket on the 20D and 30D and to the hotshoe of the 350D and 400D.

Here's Chuck Westfall's "unofficial" list of acceptable sync voltages for Canon cameras (scroll down):

If a Canon DSLR were fried by a studio strobe, it would be interesting to see if Canon would replace the camera based on Chuck Westfall's representations in the article.
