Is your old strobe safe to use on your new camera?Some strobes (and infrared strobe triggers) use high voltages in the trigger circuit. For mechanical cameras, this is fine — but many newer, electronically-driven cameras (especially electronic 35mm SLRs like the EOS or digicams — or for that matter, EOS digicams, like the 300D) can be damaged by excessive strobe voltages.
How much is too much? What voltage might my own strobe generate? This page tries to help answer those questions. It contains a table of strobe trigger voltages, a few measured by myself but most contributed by readers of this site. It also contains some information about specific camera makes and the strobes that light them.http://www.botzilla.com/photo/strobeVolts.html
