I am using this to connect an old Olympus T32 flash to a Lumix digital camera for macro shooting. It does not work in TTL (not that i expect it to) but does allow me to use the flash off camera. You must cover the 2 front pins on the unit with tape to stop the flash firing at full power. The flash then gives me 3 power settings. Cord length is more than enough to move the flash head around the subject.
Easy way to connect your OM camera to a T32 flash. It keeps full TTL functions with the flash off camera which improves the photos dramatically. The alternative is to use Olympus' fiddly accessory shoes and cables, and you need a different type for each camera. This device fits all; brilliant!
