I recently bought an eBay hot shoe accessory and it came in the mail today: I wanted this so that I could use my FL-14 flash on the E-M1 with the 4/3 lenses (to avoid cutoff), as well as to be able to use a flash off-camera via the PC sync cord. Unfortunately, the adapter only works via the PC sync attachment and when I tested the connections with a meter, there were some blanks. So I unscrewed the case and found this: Only two of the wires connect to the flash terminals, but not even correctly for the Olympus/Canon configuration. The unit is otherwise very well made and appears quite sturdy, but why the missing wires? This is supposedly for a Canon camera, where the terminals are the same as for Olympus, other than one which is not used. I've contacted the seller and I'm awaiting a response.
