  • How beautiful would the life of the flash photographer be if he had the qualities of a studio flash with the flexibility of a camera flash outside: no cables and remote control with TTL! That dream is now within everyone's reach with the Interfit S1. A studio flash 500Ws with built-in battery and controlled with a radio trigger. If you are already advanced in flash photography and you recognize the usefulness of studio flashes for distinctive photos in outside sessions, the Interfit S1 is an interesting and economical choice. Very portable, very flexible and therefore the perfect basis for creative photography. But the S1 works fine in the studio as well and it is not inferior to conventional alternatives. The absence of wires is liberating and you will see that fun in your portraits.
