司诺Siros S

A monolight combines power supply and lamp unit in one housing. There is no need for a lamp cable, making the device very handy and convenient. A battery powered monolight allows you to work completely wireless. In order to keep size and weight to a minimum, monolights are limited when it comes to flash power. Each monolight features its own controls and works independently of other monolights. The whole system is not down in case of a technical issue.

A power pack usually stands on the ground, therefore size and weight are not as critical as compared to monolights. Therefore, they offer substantially more flash power. Several lamp heads are connected to and controlled by one power pack. In case of a failure the whole system may be temporarily down. The (separate) lamp heads are much smaller and lighter than monolights.

Only Siros 800 S does feature the HS function (flash power level 4 to 10 only) , Siros 400 S is not supported.

Please note: both battery devices Siros 400 L and Siros 800 L feature the HS function.

No, as there are not only software but hardware modifications as well, this function can not be retrofitted.

Activating the broncolor HS function has a small influence on colour temperature.
However, other light sources such as daylight or ambient light usually have a stronger impact on colour temperature.
Hence, the broncolor HS function’s influence on colour temperature is alleviated in sunny conditions.
HS is meant to be used in a bright outdoor environment.

Without HS, the minimal flash duration cannot be shorter than the fastest shutter speed of the camera (X-sync).
The broncolor HS function provides a way to circumvent the restriction imposed by the X-Sync time:
1) The flash fires before even one pixel of the image sensor has been uncovered
2) The first shutter curtain starts to open.
3) The second shutter curtain starts to close (think of it as a scanning procedure).
4) The flash continues to burn (like a continuous light) and only stops when the scanning procedure is complete. For this reason we need the longest possible flash duration. The result is a great feature; now you can use a large aperture to provide an out-of-focus background, or simply freeze super-fast motions.
