All Siros L units with the latest software update are “HS” compatible. “HS” lets you use flash in combination with shortest shutter speed settings on your camera. For example, with ambient light, even with the aperture wide open (selective focus), the image can be underexposed correctly with up to 1/8000 s and Siros L still lets you set dominant and creative light effects.
Abundant power
Up to 800 joules and carefully calculated reflectors never leave you in the dark. Siros L illuminates even your largest sets or dominates the sun. High-speed synchronisation ("HS") is integrated as well.
LED modelling light
The LED modelling light consumes 25 W only but it is bright enough to build your set and focus properly. The colour temperature of 3000 K matches perfectly with the modelling light of Siros S.
Battery endurance
A single charge of the compact and lightweight battery stores power for up to 440 flashes. Full power flashes!
Impressive speed
In only 0.03 s, the Siros L can be ready for the next flash. The flash duration can be as short as 1/9000 s (t 0.1) – shorter than the fastest shutter speed of your camera!
