Product details
The ECTC technology, known from the high-end generators Scoro and Move, also controls the flash burn curve and maintains a constant color across the entire control range in the Siros S. The extensive control range of up to 9 stops and down to 4 Joules does not limit the photographer in choosing their working aperture. Additionally, the lightning-fast recharge times of 0.07 to 2.9 seconds at 800 Joules ensure that they are never left waiting. Wireless triggering is done via Broncolor RFS 2.1.
The flash durations of up to 1/8,500 seconds (t 0.1) and 1/19,000 seconds (t 0.5) in Speed mode, along with recharge times starting from 0.2 seconds, allow for capturing every perfect moment. Operation via a single rotary knob or the advanced app is intuitive. The high light output of up to 800 Joules in a robust housing ensures that no photographer is left in the dark.
The outer shell is made of a single-piece aluminum housing, which optimally protects the advanced technologies inside while giving the Siros an elegant and lightweight appearance. Control of the Siros is done through a single rotary knob, allowing for power adjustments in 1/10-stop increments and, thanks to a "Twist" function, in whole stops. The developed grip is made from a double-walled and specially coated plastic part, which is very stable and particularly pleasant to handle. The tripod mount is made of aluminum and can be used as a floor tripod together with the specially designed grip.
But that's not all. Two reflectors have been specifically developed for the Siros: a umbrella reflector that also serves as a transport protection when covered, and a size-optimized reflector L40 that can be equipped with honeycomb grids through a snap-in system. Broncolor boasts one of the most extensive ranges of light-shaping accessories, and the Siros is fully integrated into this system of unlimited creative possibilities.
