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.
For traditional studio work, the S1 also ships with an AC power pack. The multi-voltage adapter can be used anywhere in the world (100-240v).
The S1 provide, TTL, Manual, and HSS (High Speed Sync) shooting modes.
Interfit’s new S1 Remote for Canon, Nikon, & 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 (500Ws – 1.9Ws), is automatically calculated in 1/10th stop increments, and allows for +/- 3 stops of exposure compensation (adjustable in 1/3 stops).
The S1 also provides a traditional manual mode. Manual shooting mode also utilizes the entire 9 stop power range, controllable in 1/10th stop increments (2.0 – 10.0).
While in manual mode, users gain access to 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 and is manually adjustable in 1/3rd stop increments.
Utilizing IGBT technology, the S1 is able to offer short flash durations while maintaining color accuracy throughout the power range.
Flash duration ranges from 1/1,000 at full power, down to 1/9,000 at minimum power.
By shortening the flash durations color accuracy is also improved, providing consistent 5700k (+/-100k) color temperature throughout the entire power range.
S1 TTL REMOTE
The S1 camera-mounted transmitter is available for Canon, Nikon and Sony camera’s and supports E-TTL ll and i-TTL etc protocol.
Three individual groups are provided, and a working range of up to 100m (300’).
INTERFIT S1a – AC POWERED FLASH
Interfit have also released the S1a, AC only version of the S1 strobe. The S1a has all of the same features as the S1 without the battery.
This S1a is designed primarily for use in studio, or for photographers who have already invested in external power packs with sine wave inverters.
Slightly smaller than the S1, the S1a works seamlessly with its battery-powered counterpart at a 40% lower price point.
With durability a priority for portable flash units, the S1 and the S1a provide a strong and lightweight aluminum body rather than plastic.
A frosted glass diffuser dome is also included to protect the flash tube.
Both the S1 and S1a feature the widely-used Bowens® S-Type modifier mount, giving users hundreds of high quality and affordable modifier options to choose from including Interfit’s line of softboxes, reflectors, grids, beauty dishes and more.
A mini-USB cable is included with every light, allowing for firmware updates when new cameras are released.
