RFS 2.2 C Transceiver (Canon)

Item Nr: B-36.160.00


RFS 2.2 C Transceiver for Canon

In addition to offering the radio triggering and control features of the current RFS 2.1, the new “RFS 2.2 Transceiver facilitates the exciting new HS function in Siros L and Move packs. The new unit also offers the user a bright illuminated LCD screen which is easy to read and clearly indicates all settings. The RFS 2.2 transceiver is compatible with all Broncolor power packs or monolights equipped with an RFS 2 or 2.1 interface.

  The Broncolor HS function lets you now use flash in combination with very short exposure time settings on your camera. Advantages include allowing the photographer to use a high shutter speed (up to 1/8000s) to freeze motion, overpower the sun with less flash power and equipment, darken backgrounds using a high shutter speed, and most importantly shoot with a large aperture creating shallow depth of field.


        The HS function is available only for Siros L and Move flash units. All that is needed* is a RFS 2.2 transceiver, which is available for Nikon, Canon or Sony cameras. 
A change of the flash tube is not necessary, neither with Move nor with Siros L.


         *For Siros L units we recommend a software update to version 52.03. This update improves the HS function and may be downloaded from our website: http://www.bron.ch/sirosfirmwareupdate/ However, for Move a firmware update is required. This update must be made at the Broncolor service center. Further, please note that HS for Move is optimized for the use with one lamp. If working with two lamps only symmetric power distribution is possible.
