Product description

• S1 500Ws HSS TTL Battery-Powered Monolight With the introduction of the S1 500Ws HSS TTL Battery-Powered Monolight, Interfit joins the small group of manufacturers producing TTL monolights. The flash head is powered by an internal, removable 4500mAh lithium-ion battery that fits inside the head's housing. It has a 350 full-power flash capacity and can also run on AC while your battery is charging. It's controllable wirelessly at distances up to 328'.The S1 has 3 shooting modes: Wireless TTL for Canon, Nikon, or Sony; Manual Mode; and High-Speed Sync. Wireless requires purchase of a Nikon, Canon or Sony dedicated transmitter, but once that's done, you can basically treat these studio strobe units as you would your on-camera flash. In TTL, the camera's flash technology takes stock of the scene and automatically adjusts the power from 1.9 to 500Ws across a 9-stop range. If you want to fine tune your exposure, there's +/- 3 stops exposure compensation adjustable in 1/3 stops.Traditional manual mode is available for those who want complete control. Manual mode is also how you access HSS (High-Speed Sync). This mode uses the flash's top 3 power levels (from 125 to 500Ws) to allow you to access sync speeds as short as 1/8000. HSS presents a new world of exposure possibilities whether you're trying to overpower the sun, control the background's brightness, or use wider apertures.The S1 recycles to full power in 3 seconds and a fraction of that time at reduced power levels. Thanks to the incorporation of IGBT technology, the flash can also reach flash durations as short as 1/11,000 sec for the ultimate in stop-action while still maintaining a steady 5700K color temperature.The S1 ships as a complete system including a 350-shot Li-ion battery with a charger that powers it up in about 3 hours. Since the S1 is AC/DC, it can also be plugged into a wall outlet for use regardless of its voltage while the battery is charging. The S1 also includes a 7" Bowens S-Type reflector, an AD adapter and a mini USB cable.
  Compatibility and Firmware Updates
  • In order to ensure maximum compatibility with your system, Interfit offers firmware updates for download on their website. These updates can be easily installed by the user by connecting the monolight to their computer over USB.
  Complete Package
  • 500Ws monolight with High-Speed Sync, TTL for Canon and Nikon, IGBT technology, lithium-ion battery, and multi-voltage AC power pack in one complete package
  S1 TTL Remote
  • The S1's TTL remotes give the users direct control over any S1 light in any shooting mode from the camera position. This camera-mounted transmitter is available for both Canon, Nikon and Sony cameras. Having three individual groups gives users the freedom to control lights individually to create dynamic lighting ratios with a working range of up to 300' (100 m)
  Power Supply
  • Each Interfit S1 comes standard with both battery and AC-power sources. The interchangeable 4500mAh Li-ion battery provides up to 350 full power flashes in Manual and TTL modes and over 400 full-power flashes in High-Speed Sync mode. This wire-free power source gives photographers the freedom and mobility to venture out from the studio and rapidly set up and reposition lights on location. For traditional studio work, the S1 also ships with an AC power pack (adapter). This multi-voltage (100-240V) adapter can be used anywhere in the world and lets photographers continue to shoot while their battery is charging
  Shooting Modes
  • The S1 has three different shooting modes, each to serve a different purpose and shooting style. Interfit's S1 Remote for Canon, Nikon or Sony enables photographers to take advantage of their camera's TTL system just like they would with a speedlight. This automated light output uses the S1's entire 9-stop power range (500W - 1.9Ws), is automatically calculated in 1/10th stop increments, and allows for +/- 3 stops of exposure compensation
  Manual Mode and High-Speed Sync
  • For those that prefer to have complete control of their light and have time for fine-tuned adjustments, the S1 can be used in the traditional manual mode. Manual shooting mode also utilizes the entire 9-stop power range, controllable in 1/10th stop increments. While in manual mode, users can access the S1's High Speed Sync mode, reaching shutter speeds up to 1/8000th of a second. High-Speed Sync mode utilizes the top 3 stops in the power range (500 - 125Ws) and is manually adjustable in 1/3-stop increments
  IGBT
  • Utilizing IGBT technology, the S1 is able to offer short flash durations while maintaining color accuracy throughout the power range. Flash duration ranges from 1/500 at full power, to 1/11,000 at minimum power. While shortening the flash duration, Interfit was also able to improve color accuracy, giving the S1 a consistent 5700K (+/-100K) color temperature throughout the entire power range
