For several years my battery-powered off-camera flash ‘system’ has been a mishmash of equipment. I had a matched pair of optically-triggered speedlights with TTL, a fully manual radio-triggered strobe (discontinued), and a fully manual radio-triggered speedlight (discontinued). My light modifiers were another collection of umbrellas and softboxes from various manufacturers assembled with little rhyme or reason. Clearly, I didn’t have much of a ‘system’ and it certainly wasn’t very modern. It was time for something better.
