Interfit S1 AC/Battery Strobe

Availability: In Stock

  • Description


    The S1 is the first high-tech TTL HSS monolight to include intelligent TTL and HSS technology in a battery-powered monolight with an included International Multi-Voltage AC Power adapter in one complete package.

    • Through The Lens Metering in TTL Mode uses the S1’s entire 9-stop power range (500W – 1.9Ws) and is automatically calculated in 1/10th stop increments, and allows for ± 3 stops of exposure compensation
    • Manual Mode utilizes the entire 9-stop power range, controllable in 1/10th stop increments
    • High-Speed Sync in Manual Mode at up to 1/8000th of a second shutter speed using the top 3 stops of the power range (10.0 – 8.0) and is manually adjustable in 1/10-stop increments
    • Included International Multi-Voltage AC Adapter that can power the unit with or without the battery in place, maximizing battery health longevity
    • Integrated and exchangeable lithium-ion battery is flush with the flash body, offers a 350 full power flash capacity and allows for wire-free and rapid setup and repositioning of lights when power outlets encumber workflow or are not an option at a shoot
    • Color Accurate to within ±100 Kelvin using high-tech insulated-gate bipolar transistor (IGBT) technology
    • Short Flash Duration for freezing action and sports motion between 1/500th of a second to 1/11000th without compromising color consistency, using IGBT technology.
    • Integrated Wireless System with remote TTL flash exposure compensation and manual power control in three groups from camera position using the S1 Remotes for Canon, Nikon, or Sony (sold separately)
    • Frosted Glass Dome softens and disperses light evenly through large and small light modifiers alike, from large octaboxes to small beauty dishes and reflectors while protecting the user-replaceable flash tube.
    • Aluminum Construction with an attractive matte finish gives the unit greater heat dispersion, durability and weight-to-rigidity efficiency
    • Firmware Upgradeable via Micro USB Port for future fixes and features
    • Bowens® S-Type Mount is compatible with a large scope of adapter rings and modifiers such as softboxes, reflectors, and grids
