BRONCOLOR RFS 2.2 F – HS Transmitter For FUJI Announced

BRON RFS 2.2 F

 

Broncolor have announced the RFS 2.2 F transmitter for Fujifilm camera systems, which provides remote manual power control, and High Shutter Speeds (HS mode), with the Broncolor Siros L cordless strobes and Move portable pack systems.

This adds Fuji support to the existing Canon, Nikon, and Sony compatible versions of the RFS 2.2 transmitter already available for the Broncolor system.

 

BRON RFS 2.2 F

 

The RFS 2.2 F allow for individual remote manual power control of up to 40 groups of strobes, with 99 channels to select from.

As well as providing a global power adjustment, which adjusts all strobes together, while retaining existing ratios between them.

The 2.4GHz transmitter is powered by 2 AA batteries and provides a single pin pass through hotshoe, PC sync port, AF assist light, and dot matrix LCD interface.

The RFS 2.2 F are also backward compatible with the Broncolor Scoro and Senso RFS 2 protocol.

 

 

The Broncolor HS mode currently uses the “Long Burn” or “Long Duration Sync” method, rather than pulsing the flash like traditional HSS.

Enabling the HS mode on the Siros L and Move strobes adjusts and optimizes the flash curve to allow shutter speeds up to 1/8000th of a second.

The RFS 2.2 transceivers are pre-programmed to provide the optimum shutter delay timing for each camera model.

Though a HSMA menu (HS Manual Adjust) can also be used to choose an optimal exposure delay setting manually.

 

 

 

PRICE AND AVAILABILITY

 

The Broncolor RFS 2.2 F transmitter for Fuji are expected to be available late December 2017 from $112 –

    It doesn’t have 99 radio channels. It has 40 and the channel is automatically selected (according to the manual). The 99 “studio channels” seem to correspond to the “Wireless ID” that has been introduced in the Godox XPro triggers. So many lights and triggers can share the same radio channel but only lights and triggers with the same studio channel number will communicate.

    It’s obviously a customised Godox X1 trigger. It would be interesting to know if the RFS 2.2 radio protocol is identical to the normal Godox protocol. It’s also unclear what the HS mode is. For the older Broncolor lamps it must be some sort of hypersync. The Soros L and Move devices look like they may be IGBT flashes in which case they would use HSS.

    One interesting feature of the trigger is that it can be configured to act as a receiver and so trigger a non radio enabled light.

      Thanks John, I was just trying to make it clear what your practical options are in terms of groups and channels available, as the irregular terminology Broncolor have used makes it pretty confusing. I have removed the term radio now though.

      I would need to check on the HS mode again, though unless by optimizing the flash curve they do actually mean pulsing the flash, then its just extending the flash durations, and using the long burn method (like Elinchrom are doing).

      The radio protocol will not be compatible with Godox, because it was designed to be backward compatible with Broncolor’s previous RFS 2.1 radio system which has no relation to Godox.

      The Canon, Nikon, and Sony versions of the RFS2.2 are titled as “Transceivers”, though the Fuji version is called a “Transmitter”, and there is no mention of the radio receiver mode, so I’m not sure if this Fuji version also has a receiver mode.

        Hi Elvis!

        The Broncolor product page for the Fuji trigger says it will act as a receiver https://www.bron.ch/broncolor/products/accessories/showproduct/rfs-2-2-f-transmitter-fujifilm/

        You will have to forgive me the geeky pleasure I take in nit picking:)

        What’s of real interest to me is why Godox would bother with doing a deal with Broncolor to make a custom version of the X1 triggers. The volumes are not going to be very large. If they have implemented a completely new wireless protocol they would have diverted engineering resource from making new products to customising the X1 firmware and they will have an ongoing support commitment for the customised code. For it to make commercial sense the revenue stream would need to be quite substantial or there is a non financial advantage to be had from the deal (e.g. Broncolor have some technology to trade for the trigger technology). Alternatively Broncolor may just have licenced the Godox firmware and hacked it themselves.

        A possibility is that the trigger implements the RFS2.1 protocol and a slightly modified Godox protocol. It would use the 2.1 code to talk to the old units and the Godox protocol to talk to the Siros and Move units. The Godox protocol would need to support 40 groups and the 99 studio channels. Upping the number of groups may not be a big problem (depends if they have 4 bits or a byte to to hold the group number in the message). We’ve seen that Godox has added the studio channel functionality in the firmware that comes with the XPro triggers.

        Implementing the two protocols would give Broncolor the opportunity of phasing out the old protocol as it can migrate the rest of the product line to RFS2.2 in its own time. At that point Broncolor can just sell rebadged XPro triggers and, as a bonus, users would be able to use something like a V850 as an on camera controller thus allowing Broncolor to approximately match the Profoto B2, B1, A1 offering.

        Isn’t baseless speculation fun!
