Broncolor Siros 400 L WiFi / RFS2 Outdoor Kit 2

SIROS L – Cordless, Compact, Fast and Powerful

Cordless, compact, fast and powerful, the new Siros 400 L is broncolor's latest battery-powered flash head for professionals. Whether you're shooting in the studio or out in the field, the Siros L is the ideal start in professional, battery-powered photography, and perfect when available ambient light needs supplementing with flash. Made from aluminium, this stylish, simple to use head offers up to 440 flashes at full power per battery charge, colour constancy and both very fast, and also long, flash durations.

All Siros L units with the latest software update are “HS” compatible. “HS” lets you use flash in combination with very short exposure time 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. All you need for this is the RFS 2.2 trigger, which is available for Nikon, Canon and Sony cameras.

Siros L is battery-powered

A single fully-charged lithium-ion battery stores enough energy for a Siros 400 L to flash more than 440 times – and it does that at maximum power! A miracle? No, quality!

Siros L is fast

In only 0.03 seconds your Siros L is ready again. The flash duration can last less than 1/9000 s (t 0.1) or 1/19’000 s (t 0.5). Truly miraculous times.

Siros L is simple

Very simple operation using the single rotary controller. Alternatively you can use the advanced, intuitive app. Either way using Siros L is fun.

Siros L is powerful

The high light output, up to 800 J, leaves no photographer standing in the dark – it can even challenge sunshine.

Siros L is LED

With its low power consumption, the 25 Watt LED module provides bright modelling light at a colour temperature of 3000 K. The light characteristics is absolutely comparable with the modelling light from a mains-operated Siros S.

Elizabeth D. ★★★★★

I was a bit worried about the weight, but the built-in handle makes it easy to carry around the shoot. The recycle time is incredibly fast, even at full power—I never missed a shot while waiting for it to charge back up.

Robert ★★★★★

The Siros 400 L's compact design really shines on location—I can toss it in my bag without the usual weight, and the cordless setup means I'm not hunting for wall outlets mid-shoot. The RFS2 integration with my remote triggers has been flawless so far, and the recycle speed is impressively quick for

Lucy A. ★★★★☆

The battery holds up through a full day of location shoots, which is exactly what I needed for outdoor work without dragging a generator along. Only wish the carrying bag had a bit more padding for the price, but the flash output itself is clean and consistent.
