For over 50 years broncolor
has refused to compromise on the quality of light.
In this sense, Siros is a true broncolor product. The Siros S includes
the ECTC technology you know from our high-end Scoro and Move power
packs. The enormous control
range goes up to 9 f-stops, resulting in output as low as 2 ws which
gives the photographer an unrestricted choice of aperture. And the
lightning-quick charging time, 0.02 to 0 .90 s at 400 ws, means you
never have to wait. broncolor offers the world's most comprehensive
range of light modifiers, and Siros was built to be fully compatible
with this system to provide unlimited creative possibilities. Two
new reflectors have been developed especially for Siros: An umbrella
reflector, which is equipped with a cover that also serves as transport
protection, and a size-optimised reflector, the L40, with a snap-in
system for mounting honeycomb grids.
Siros is fast. With flash durations from 1/8000s (t0.1) or
1/13'000s (t0.5) and recycling times from 0.02 s you can capture every
moment perfectly.
Siros is simple. Operation using either the single rotary controller
or the advanced app - both are intuitive.
Siros is powerful. High light output, up to 800 ws, in a robust
housing leaves no photographer standing in the dark.
Siros is Swiss. Swiss precision and broncolor quality - inside and
out.
Siros is family. Siros is available in standard and S variations,
and in 400ws and 800ws versions.

When "instant" counts, it is time for SPEED.
In Speed Mode, you can set the fastest flash duration as the exclusive priority. When using Speed Mode, constant color temperature functions (ECTC) are suppressed.. |
 |
The second generation of our patented ECTC (Enhanced Color
Temperature Control) technology, which adapts flash voltage and flash
duration to each other, achieves a constant color temperature over
the entire output range.
|
 |
Flash duration and light output are the two decisive factors in light
control. A microprocessor in the Siros will calculate the shortest flash
duration for a given output for you. This enables rapid flash
sequences with up to 50 flashes per second. |
 |
With Siros S, you have the choice of 9 F-stops to set the flash output you need
- from the top power level all the way down to 2ws. . |
