This can be more than a bit much for the microprocessor triggering the flash in the M6TTL and the M7 (and other cameras as well). It can easily fry the camera's electronics. It is simple to use a voltmeter to check the voltage across a fully charged flash. Safe syncs go between the flash and the camera to reduce the sync voltage to a more manageable value. Here are the safe syncs that B&H offers: http://www.bhphotovideo.com/bnh/controller/home? ci=1&sb=ps&pn=1&sq=desc&InitialSearch=yes&O=SearchBar&A=search&Q=*&shs=s afe+sync&image.x=7&image.y=7 John Collier On 1-Feb-05, at 3:03 PM, Richard wrote: > WHat's a safe sync?

Or should the sync socket do it on its own.
