3 Ways to Sync Your Strobes to Your InstantKon RF70 / SF70
- Connecting the External Flash
- RF70/SF70 includes a 2.5mm audio jack to trigger external flash units.
- Make sure you’re using a 2.5mm Cable (Mono Jack Plug)
- The flash will not work with shutter speeds faster than 1/125.
(For SLR670-X: Use 1/60 or slower speeds with external flash for the best results) - Turn off the TTL function of your flash.
