Does work High Speed Sync for V6 and RF60?

Hello Cactus Comunity,

In the V6 Manual is stated the followings: 

"The V6 will work as a wireless flash commander while supporting all the automatic features (e.g., automatic flash output via TTL metering,AF assist light, second curtain sync, high speed sync/FP shutter) provided by the TTL flash system."

I cannot setup and use the High Speed Sync functionality with V6 and Nikon SB800 off camera neither with RF60 flash.
So, does Cactus offers HSS with V6 and RF60???
I bought 4xRF60 flashes and other 3xV6 having in mind to use the system outside with HSS functionality but I realized that it doesn't work.

Please respond to my query.

Thank you in advance!

Regards, Vali Goaga Photographer

    The sentence before the passage you quoted from the V6 Manual is important:


    With TTL pass-through, the TTL flashes behave as they would when directly connected to the camera hot shoe.


    What you quoted only applies to a flash mounted on an on-camera V6 with TTL pass-through enabled.

    Via radio communication, no TTL features such as HSS are supported for third-party flashes. If the Nikon SB800 has a way to manually engage HSS then you can use it for HSS applications with the V6 in the same manner as the RF60.

    The RF60 supports HSS with the V6 by allowing you to manually engage HSS on the flash itself. Once you do that, there are a number of alternatives:
    • Up to certain shutter speeds, you can just shoot as normal (just triggering the RF60 flashes with the V6), as long as no black bars creep into the image.
    • You can use the RF60 in "HSS Sympathy" mode (section 11.2 in the manual) by optically triggering it from a camera mounted HSS-capable flash.
    • You can optically trigger a V6 in transmitter mode near a camera mounted HSS-capable flash and use the V6 to trigger off-camera RF60 flashes (or other flashes that support manually engaging HSS mode).
  • Hi,

    How can I apply the 2nd and 3rd bullets above if I am about 100 m far away of the RF60 monted on a tripod and close to subject in bright sun light where the shutter speed needed is around 1/1000s????


  • I was expecting the V6 to work very well with HSS in radio mode as Pocket Wizard does (about 1/8000s can take picture in sun light).

    Is it possible to have this functionality working for this model V6 in the near future? Can this be included via an firmware update? 
    When shall we expect to have this functionality available?
  • I bought a pair of V6 tranceivers with the intention of doing Highspeed Sync as advertised up to 1/1000, which would take care of most of my needs for doing LowKey outdoors in shade.   However even at 1/250 I have black bars showing up in my photos.  At 1/800 I get totally black frames.

    I am currently using a Nikon D90 with SB800 and SB600 flashes and have had no issues with Highspeed flash using the CLS system with the built in flash and the above flashes.

    At close range I can do Highspeed Sync using the Nikon CLS system outdoors up to at least 1/4000 without issue - using the Built in flash to trigger both flashes.  

    I shoot with another photographer who also shoots Nikon both FX and DX format cameras, using SB800   He wanted to see how this works out for me before purchasing some V6s.

    Are their any plans to update the firmware so that Highspeed sync will work ?

    Thank you
    Ben

    In this scenario, you cannot apply the approach described in the 2nd bullet, but you can use the approach described in the 3rd bullet.

    Note that in this approach the V6 transmitter that is optically triggered is close to the camera. I often just use my left hand to hold the V6's sensor against the on-camera flash.

    The transmitter V6 can then trigger RF60s and other V6s across large distances.

    Consult the manual for how to set up the V6. You basically have two options:
    1. Ignore the preflash, or
    2. Sync on the preflash plus setting a delay on the V6 to postpone the firing of the off-camera flashes until the main flash goes off. You'll need this second approach once you get into the really fast speeds.

    With this approach, I have been successfully taking images in bright sunlight at 1/2000 or higher.

    You may have misread the advertised "max. 1/000s sync-speed" as "max. 1/1000s shutter speed".

    With cameras that support 1/1000s sync-speed, the V6 supports taking pictures at that shutter speed.

    With cameras that only support a sync-speed of 1/180s or 1/250s, one has to use (manual) HSS to go beyond those speeds without getting black bars.

    The V6 does not support the CLS system, but it is possible to use the RF60 to achieve HSS. Perhaps my previous post helps already but the RF60 manual goes onto more detail.

    Other flashes may work as well but only if you can set them to HSS mode manually, i.e.without requiring communication with the camera.
  • Dear Class A,

    you got kidding me ...with the scenario above :):):).
    How can I use it when I am doing wedding photography and I have only 10-20 min to take pictures with Bride and Groom????!!!!!
    You know what that means??? DO I really need to take care of such work around??? 
    I need to have the right equipment that I am rely on not to keep in my left hand a V6 transceiver which will trigger the RF60.
    Guys, I had the impression that Cactus provides very serious products that can compete with Pocket Wizzard, Radio Pops, etc. that's why I invested in their equipment...I hope i was not wrong

    Also, you did not answer to other questions posted above::

    I was expecting the V6 to work very well with HSS in radio mode as Pocket Wizard does (about 1/8000s can take picture in sun light).

    Is it possible to have this functionality working for this model V6 in the near future? Can this be included via an firmware update? 
    When shall we expect to have this functionality available?

  • @goghitza I am sorry to hear you had this false impression that Cactus triggers have HSS capability. It's simply not a TTL flash trigger.

    As you know HSS is a TTL feature, and all Cactus triggers released to date are all manual flash triggers. So, just like a manual flash, it does not support HSS. What's special about the V6 is that it has the ability to control TTL system flashes, multiple system all at once for that matter, but it does not support any TTL features wirelessly via the transceivers.

    It is still a manual trigger at its heart - it just happens to be able to control TTL flash and supports TTL pass through. Maybe this gives you the impression it also support TTL's function - HSS.

    Certainly we do not expect professional photographers like yourself to fiddle with the many settings to achieve HSS during a location shoot at a wedding / pre-wedding.  If you need to shoot at speeds above your camera's x-sync speed (usually 1/250s) such as 1/8000s, you simply need a TTL flash trigger.

    Your impression is legit. Cactus does provide very serious products and since the launch of the V6 last year in 2014, it is still the World's First and Only flash trigger that can wirelessly and simultaneously control flash power of multiple TTL system flashes. As a manual trigger, it may be fair to say none can compete.

    On that note, we are working on version that will support HSS and the current V6 will be supported by a simple firmware update.  

    As to when, we're hoping to have it available sometime in 2015. ;)

    Thank you for your time and patience and we welcome any suggestions.

    Antonio, these are exciting news.

    Are you saying the V6 firmware update will make a V6 compatible with a new version that will support HSS, or are you saying the V6 as it is, will support HSS through a firmware update?
  • Hi Guys!
    Hi Antonio!

    This is a great news, I can't wait to get HSS available on V6 :). 
    In that case you really compete the Pocket Wizard which is far away with the price by V6.

    Good luck with the development and bring us good news as soon as you can!

    Regards, Vali Goaga

  • Great news huh!? :D

    @Class A : a firmware update is required on the current V6.
    @goghitza : thanks for the encouragement! 

    I will keep y'all posted!!

  • Hi Antonio,

    what will the V6 be able to do after the firmware upgrade?

    Will it be able to support HSS on its own or will it be compatible to a future model that supports HSS?

    Compatible when used with a future model.

    I don't know the details as to what other function it can do after the update, so HSS for now. ;)

  • Hi. Tell me please, do I have any chance to shoot in HSS(high speed sync) with a Canon EOS mark II, Cactus V6 and a RF 60, without any help from another TTL flash ?
    Thank you
  • Hello @Valerian,

    With the current V6, the answer is no.

    If you are not already a V6 user, you should wait for the new model:

    Yes, if you pair the V6 with a system-dedicated trigger that supports HSS. You can piggy-back the triggers onto each other on the camera and then need to connect them with a sync-cable.

    Brian Hursey used to have a detailed description of this setup at http://brianhurseyphotography.com/blog/how-to-cactus-rf60-radio-hss/ but the site does not appear to exist anymore.

    If I were you, I'd wait for the V6 Mk II, but if you do have a system-dedicated HSS trigger anyhow, you can perhaps use this workaround until the Mk II becomes available.
  • Good day Antonio:

    After watching all the setup vid's on YouTube and seeing what this transceiver can do, I have to say if you were to combine HSS ability as well as the abilities currently available on the V6 I am confident many people (myself included) would be reaching for their credit cards to purchase this product. The product adds convenience and extra creative ability as it is. The only thing missing for me is HSS please push the development dept. as much as you can for this aspect/ability. I am a Pentax system owner (hopefully soon a K1)
  • Hello @landor789

    It sure is coming. If you scroll two posts up you will see a link to the Sony version (prototype at the Photography Show) reported by Amateur Photographer Magazine.

    There will also be a version for other standard ISO hot shoe cameras including Pentax. We estimate availability in June.

    Many are talking about the Pentax K-1 lately. Do you plan on getting it right away? Some say the price would stay for good unlike their previous models. Keep us posted!
