SHANNY – SN600EX-RF Speedlite – Short Review

Shanny SN600EX-RF


The Shanny SN600EX-RF Speedlite with Master and Slave mode for the Shanny RF Radio system are now available from $150 with shipping.

The SN600EX-RF have radio transceivers built inside, compatible with Shanny’s 2.4GHz RF radio system, which also includes the previously released SN600C-RF Slave flash, and SN-E3-RF transceiver units.

The Shanny RF system is not compatible with Shanny’s existing RT flash system. This RF system is designed to compete with other popular and inexpensive ETTL and HSS enabled RF style radio flash systems like the YongNuo YN-622C and Pixel King Pro (though not compatible with them).

The advantage the Shanny RF system currently has over the YN-622C, is flash units with radio transceivers conveniently built inside.


Another very notable advantage to the new SN-600EX-RF flash, and Shanny’s RF system now, is the exceptional range with a flash unit as the Master transmitter mounted on the camera. The best range we have seen from radio flash to radio flash so far.

Though the main limitation to Shanny’s current RF system, is that they follow the protocols of Canon’s old Optic Wireless system very closely, and therefore share the same limitations. Like not being able to mix ETTL and Remote Manual flash groups, or no Second Curtain Sync available in Master Mode.


Once again, apart from the additional built-in 2.4GHz RF radio receiver, and USB port for firmware updates, the SN600EX-RF are built on the same flash body and hardware as the original Shanny SN600SC. Which have previously been reviewed, described the full functions and features in more detail here.

The SN600EX-RF are around 0.2 to 0.3 stops less powerful than the earlier Canon version SN600SC though (which are basically equal the Canon 600EX-RT).


Shanny SN600EX-RF


The SN600EX-RF provide both RF Master and Slave modes.

So they can be used as either Master unit mounted on the camera, or wireless radio Slave flashes.


Shanny SN600EX-RF


As part of the Shanny RF system the existing SN-E3-RF transceiver units can also be used as either a transmitter on the cameras hotshoe, or as additional receiver units allowing Canon ETTL flashes to be included in the system with full functionality.

(MK II sytle Canon flashes are needed for Remote Manual Power control).

SN-600C-RF or SN600EX-RF can be used as Slave flash units.




The SN600EX-RF do not include any Canon or Nikon Optic Wireless Master or Slave flash functions though. They do include the basic S1 and S2 optic slave modes.

As an on-camera flash alone, the SN600EX-RF provide full function with ETTL, HSS, SCS, and control of the flash through the camera menu.

(Note – SCS (Second Curtain Sync) is not available in radio master mode).

Shanny have produced quite a number of flash models for Canon already, so as with the previous models the SN600EX-RF’s ETTL base exposures appear to be within a stop of the Canon 600EX-RT.

And Flash Exposure Compensation all appear to work fine. On and off camera.



A standout feature appears to be the SN600EX-RF’s radio range when used as a Master transmitter unit mounted on the camera.

With the one sample flash supplied at least (and using the SN600C-RF as the slave flash) the range is definitely beyond what the Canon RT system is capable of. Line of sight providing over 100 meters with completely consistent results. I ran out of room to test just how far these may go.

With SN-E3-RF transceivers used as transmitter or receivers, the range was not quite as good as with the SN-600EX-RF as transmitter and SN600C-RF as slave.

We will have to do more comparisons with the SN600EX-RF in different environments, though at this stage they appear to be leading in range capability between TTL radio flash units.



Unfortunately the main limitation to Shanny’s RF system though is that they currently follow the protocols of Canon’s old Optic Wireless system very closely, and therefore do not have a GR / Group style interface like the more recent Canon RT system provides. The Group mode allows mixing of ETTL and Remote Manual flash groups, as well as turning groups on and off individually.

The recent Pixel X800C radio flash shares the same limitations, though at least the King Pro used as transmitter do provide the more versatile Group style interface. Shanny’s SN-E3-RF transmitter currently relies on the cameras flash control menu (having the same limited Canon Optic Wireless style interface). Though Shanny are likely on a new transmitter unit.

Second Curtain Sync is also not available in Master Mode, as that is the way the Canon Optic Wireless System operates (SCS is disabled when “Wireless Function” is Enabled).

I have suggested to Shanny that the Nikon style master interface and features would make the SN600EX-RF far more practical, if it may at all be possible to update this functionality in the future.


Otherwise the SN600EX-RF and Shanny RF system appear to be very simple and reliable. Its just a pity that Shanny did not finish their RT system well first, and concentrate on putting all the good features and performance into that. As now their are currently 2 separate systems with various advantages and disadvantages in different areas.




The SN600EX-RF like all current Shanny flash models share the Canon 600EX-RT style interface.

The Shanny LCD displays are not very high resolution compared to most other dot matrix displays. Though if anything this has turned out to be an advantage, with the characters easy to read from a distance.

A slightly sticky main control dial has been an on running issue with Shanny flashes, though generally not too much of an issue.


Shanny SN600EX-RF



The SN600EX-RF’s radio master interface currently follows the function options in the same way as the Canon Optic Wireless system.

This means that ETTL and Manual flash groups must be selected separately. And ETTL and Manual groups can not be mixed together, for on or off camera flash use.

The group options are ALL, A:B ratio, and A:B C, where group C is an independent group to be used as a background light (and should not be aimed at the subject).


Shanny SN600EX-RF



Manual again provides 3 individual groups, though only 2 groups can be seen on the flashes master interface at once.

The only option then to turn these manual groups ON and OFF is by selecting the group options: OFF / ALL, A:B, or A:B:C, to be set as ON.


Shanny SN600EX-RF



A new feature to the Shanny RF system is the option of Auto and Manual remote flash zoom setting.

At the time of writing this the remote zoom setting feature is only enabled between the SN600EX-RF flash units. Though this may possibly be able to be implemented on SN600C-RF flashes via a firmware update in the future (there is no promise of that though).


Shanny SN600EX-RF



There is also a new Custom Function C.Fn24 which currently has no function.

Shanny are not commenting at this stage on what this is for, though we suspect its likely a mode that will correspond with coming products like the updated SN-E3-RF transmitter or transceivers.


Shanny SN600EX-RF




Importantly the SN600EX-RF do include a micro USB port in the flashes battery compartment for firmware updates.

At the time of writing this though, Shanny have not reached the stage of providing any firmware updates for current owners.

(SN600C-RF flash model shown below)


Shanny SN600C-RF





As noted previously, Shanny are no longer consciously seeking or maintaining ongoing compatibility with YongNuo equipment (or any other third party brands), only with the original Canon equipment.

Unlike the current SN600SC though, the SN600EX-RF do (at the time of writing this) appear to have full function when used with the YongNuo YN-622C V1.2 (built from January 2015), as well as the original YN-622C.

That is with a YN-622C as receiver attached to the SN600EX-RF foot (not any direct link with the YongNuo radio system).

As mentioned above though, this compatibility could change over time with updated models, and firmware updates etc, as Shanny are no longer maintaining compatibility with YongNuo equipment.



The Phottix Odin or Pixel King Pro receivers will not currently fire the SN600EX-RF flash at all.




Once again, apart from the built-in radio receiver, slightly lower power, and added USB port, the SN600EX-RF are otherwise built on the same flash body as the original Canon version SN600SC,

And more detail on recycle times, flash patterns, AF light, ports etc can be seen in the SN600SC review here.

FLASHES – Shanny SN600EX-RF, SN600C-RF





The Shanny SN600EX-RF are looking to be well resolved, with notable range and reliability.

The lack of Gr Group style interface (allowing mixed ETTL and Manual groups etc) is a considerable step backwards from the Canon (and Shanny’s own) RT system though. Or even the YN-622C system Shanny are trying to outclass with their built in radio flashes.

Shanny are working on a new RF transmitter (or possibly new transceivers) with their own built-in interface to replace the limited SN-E3-RF. Though its still unknown if these will provide a Gr Group style interface either.


Where the Shanny RF system may be looking very promising though, is for the coming Shanny RF system for Nikon.

If the Nikon version can provide the same range and reliability, with the Nikon Group style Master interface and function, then Shanny may be onto something impressive, and very much needed for the otherwise still quite neglected Nikon owners.

Shanny – SN600C-RF & SN-E3-RF Review

    It seems C. Fn24 mode 2 is a compatibility mode with YongNuo YN560-TX 🙂

      Hi Alexander,

      Thanks for that.

      For anyone else following this though, we have not been able to see any communication between the YN560-TX or YN560 IV (as transmitter) with the SN600EX-RF as slave flash as yet.

      There is definitely some connection with the C.Fn24 radio mode to the YongNuo system though, as the RF-605 and RF-603 II will fire the SN600EX-RF at times. So far this is very inconsistent though, and also sets off the flashes modelling light feature at times.

      So at the time of writing this its not really clear if this feature is something that is yet to be refined, or if this is possibly something Shanny started when they where more interested in YongNuo compatibility, and have since put aside.

      Shanny have been very slow though with any clarification on what this function should be from the beginning.

  2. Alexander 6 years ago

    Yes, while I too failed to get a full compatibility.

    I think it is worth the wait 🙂
    It is likely that radio products by Shanny may have great potential for compatibility with different protocols.

    Hi Flash, I have question.
    I have a few YONGNUO 600 EXs and they all overheat prematurely from constant HSS use; but my original Canon flash does NOT do this; I am assuming it slows down the recycle down or just cools better. It’s affecting my shoots so Im wondering how the Shanny fare in full power HSS pops and overheating… is there ANY way I can test this indoors? I tried putting my flashes in HSS and shooting manual 1/8000 but it doesnt seem to exhibit any overheating but when I actually shoot (I shoot in ETTL); it overheats (the YONGNUOS).

      Hi Donald,

      What power level are you setting the flash to test then?

      I haven’t had a chance to actually review the YN600EX-RT yet, and compare the heat protections etc. Though most third party flashes can only provide around half the pops the Canon 600EX-RT can at the same settings.

      The flash zoom setting can make a big difference as well, if you can set the flash to 50mm or more it provides some distance between the flash tube and front diffuser panel, so the heat protection generally allows more pops at the longer zoom lengths.
