Godox TT685-series external flash units: another demonstration of cross-compatibility

The following product photos show the bottom of Godox X2T-series wireless flash triggers for Canon, Fujifilm, and Olympus/Panasonic digital cameras. The pin pattern on the flash triggers is the mirror image of the pin pattern on the camera hotshoe.

Notice the pin pattern varies by camera brand. One pin — the power pin — is located in the same place on all types of flash brands. The other pins are used to control functions such as Through The Lens flash metering (TTL) and High-Speed Sync (HSS). This is why almost any relatively new external flash unit can be used in Manual mode with almost any relatively new digital camera, but TTL and HSS are incompatible unless the flash is mounted on the hotshoe of a camera with a matching pin pattern.

Cross-compatibility among Godox TT-685-series external flash units

The beauty of the Godox system of external flash units is it’s truly a system — all units that I own and have tested extensively are cross-compatible.

For example, when a Godox TT685F for Fujifilm cameras is used off-camera it can be fully compatible with a Godox TT685O for Olympus and Panasonic cameras (including TTL and HSS functionality) when it’s fired by a flash trigger such as the Godox X2TO. It’s amazing to watch!

The following quick-and-dirty video is another demonstration of the cross-compatibily among Godox TT685-series external flash units.

A Godox TT685F flash for Fujifilm cameras is featured in the preceding video. The flash was fired remotely using a Godox X2TO wireless flash trigger for Olympus and Panasonic cameras.

Tech Tips

An Apple iPad mini 2 was used to shoot a raw video clip that was post-processed using Apple iMovie. The magic wand tool in iMovie was used to automatically enhance the audio and video quality of the clip. Audio quality was improved significantly by the magic wand tool!
