Broncolor Siros 800 S overview

  • 1Description

Providing a 800Ws output in a compact design, the Siros 800 S WiFi/RFS 2.1 Monolight from Broncolor is a reliable studio flash unit with Wi-Fi connectivity and a built-in RFS 2.1 receiver for wireless control and triggering. It has a 9-stop power range which is adjustable in 1/10 or full stop increments for great control over light output. The Siros S is also quite fast with a flash duration from 1/8000 - 1/500second and a recycle time of 0.04 - 2.9 seconds depending on power settings. Additionally, the monolight has a halogen modeling light.

Built into the Siros S is a specialized Speed Mode that speeds up the charging time and flash duration to provide a fast sequence of exposures, up to 50 per second at the fastest setting. Also, the unit has a USB connection for software updates and is fan cooled for temperature control. An integrated reflector and mount are included for adding modifiers to the light.

When the Siros is connected to a Wi-Fi network, each light can be identified by a different-color LED and can be easily controlled using the bronControl app for smartphones and tablets
With the integrated Broncolor RFS 2.1 receiver, users can use the RFS 2.1 transmitter for remote control from the camera
Cut-off technology uses a microprocessor to calculate the flash duration to an output, enabling sequences with up to 50 flashes per second
Enhanced Color Temperature Control technology adapts flash voltage and duration in order to achieve a constant color temperature over the entire variation range
Individual power distribution means the unit has controllers for each lamp in order to have greater control over the flash power range
Speed mode reduces flash duration and charging time while reducing the maximum power in order to achieve a series of rapid exposures without overheating
Single rotary control for flash power output setting, a slight turn provides 1/10 stops while a "Twist" function allows for whole stops
Internal discharge when power is reduced
Grip features double-wall plastic with a special coating for durability and comfort
Aluminum stand adapter can be used with the handle to function as a built-in floor stand
Standard sync port and built-in photocell are available for more elaborate triggering setups
Black aluminum body construction
Designed and developed in Switzerland

    Broncolor Siros 800 S reviews

    Siros 800 S WiFi/RFS 2.1 Monolight is rated 4.0 out of 5 by 3.
    Rated 5 out of 5 by from Best in class Perfect monolight strobe, compact, constant colors at all times, 9 f-stops, very intuitive to use, from 1/1000 (800 J) to 1/19000 s (3 J). I have two 800s and one 400s + an external DC/AC battery for outdoor shooting. Considering my needs (studio + outdoor shooting), it is a far much better versatile combinaison and reasonably priced choice than to having one Move 1200 with only 2 heads (as far you do not need 1200 J on one head or need something very compact-packed). And there is no compromission with the global performance.

    Rated 3 out of 5 by from Good light, not good service/support In terms of its performance it is a first quality equipment. Power, consistent light out put, short flash duration... first class. Cons: - Heavy (I act cautious when it's attached to my Para 133) - Limited usability and brand support (supports only two known DSLR brands). I cannot use its HS feature with my medium format GFX camera. You stay limited to your camera's sync speed, because there is no compatible RFS trigger. - The Control App is good, but limited to your phone or iPad. I wish I could control the lights while shooting tethered from my computer.

    Rated 4 out of 5 by from Great product, great price Love the Siros lights, we have 4 and run them through the app. We run them almost every day and have had no major problems yet. I will Say is Broncolor is looking at this that they could improve their soft box mount a little. No major problems, it just has some room for improvement
