Another nail in the coffin of Canon/Nikon relative duopoly – Cactus introduces cross-platform radio remote TTL flash system

Saturday, March 25th, 2017

Since the 1960′s, Canon and Nikon have enjoyed a relative duopoly in the world of system cameras, especially amongst professional photographers.

In the late 1980′s, Canon took the lead with their totally redesigned lens mount system allowing fast AF, and it is only in the last decade or so that Nikon has again taken the lead with their even better AF tracking and metering technologies.

But as Olympus has shown with their Olympus OM-D E-M1 Mark II camera, the advantages of the Canon and Nikon dSLR systems are rapidly being lost to ever improving technological advances, especially with sensors, AF and mirrorless systems which, particularly in the case of Micro Four Thirds, offer adequate image quality (often better edge to edge image sharpness) , smaller, lighter, less expensive kits more suited to our travel and hiking needs, more accurate and often faster AF, faster burst speeds with accurate continuous AF, much better image stabilisation, hand holdable super telephoto reach as well as better run and gun hand holdable 4K video.

Part of the successful marketing strategy of Canon and Nikon is keeping their users loyal to their brand – once they have invested into their system, much like Apple users, they are generally too heavily invested to swap brands or even to use other brands with different user interfaces or incompatibilities.

If you had, or wanted to use Canon lenses to their full capability, you had to buy Canon dSLRs, likewise for Nikon.

If you had a Canon system, you had to buy Canon-specific flash systems if you want TTL or remote radio TTL flash – likewise for Nikon.

Canon dSLR owners could use other lenses, even Nikon lenses but with sacrifice of fast AF.

Nikon dSLR owners could not use non-Nikon mount lenses due to a physical design issue – the distance from sensor to lens mount is too long.

Enter the new world of cross-platform utility

My last blog post espoused the potential utility of using Sony full frame mirrorless cameras with a Sigma MC-11 adapter which at last provides fast AF with most Canon EF mount lenses on Sony cameras, but in particular, the Sigma branded ones.

This allows photographers increased choice – they could get a mirrorless full frame camera with a different sensor characteristics plus sensor based image stabilisation and face AF for their Canon lenses with better feature sets at the same price as the entry level Canon 6D dSLR- seeing that Canon has not shown interest in creating such a camera.

Now, Cactus has massively increased cross-platform utility by announcing a free firmware upgrade to their Cactus V6 II radio remote control flash system, which allows Canon, Nikon or Olympus flashes to be used with most other brand cameras with either on-camera TTL or remote radio cross-TTL capability!

This is awesome, but wait, there’s more, the Cactus V6 II x-TTL also allows:

  • remote control of flash unit output, even below 1/128th level for ultra short, motion-stopping shots
  • automatic zoom level control of flashes
  • Super FP or HSS mode (but Pentax and Sony cameras need a brand-specific flash for this to work)
  • Power Sync mode to allow a faster flash sync without losing flash output as occurs in Super FP/HSS mode
  • two unique new flash exposure modes:
    • Flash Compensate – store a desired flash exposure that will automatically adjust according to changes in camera settings.
    • Flash Power Lock – lock flash power output after a desired TTL exposure is achieved, for consistency in repeat shooting.

See my wikipedia page for more information of remote control of flashes.

 And, of course, this also also fantastic news for Micro Four Thirds users who can now have radio TTL flash on their Olympus and Panasonic cameras – even with Canon flashes!

At last, radio TTL remote flash coming to Micro Four Thirds – PocketWizard FlexTT5 for Panasonic

Wednesday, September 21st, 2016

One area where Micro Four Thirds users have been seriously neglected is in radio TTL remote flash capability.

Micro Four Thirds users have had to settle for either light-based line-of-sight TTL remote flash, or non-TTL radio remote flash.

A big player in third party radio TTL remote flash technology is PocketWizard who have had their FlexTT5 units available in either Canon, Nikon or Sony versions for several years now.

This week PocketWizard have announced a Micro Four Thirds version – albeit at this stage only compatible with Panasonic GH4 camera in combination with either a Panasonic DMW-FL360L or DMW-FL580L flash but will support radio remote HSS TTL as well as normal remote radio TTL mode and their proprietary Hypersync non-TTL mode.

These units thankfully are firmware upgradeable, and they do intend adding support for other cameras and flashes, and there is no physical reason why this could not be extended to Olympus cameras and flashes given they use the same hotshoe pins (although Olympus has an additional power supply pin now which would be ignored by this units without issue) and essentially the same TTL technologies.

The units will cost $US186 per unit or $US299 for a pair (you need one for the camera and a receiver for the flash).

 

 

Radio remote TTL flash for Micro Four Thirds?

Saturday, September 28th, 2013

As much as I love Micro Four Thirds, there is one area which I would really love Olympus and Panasonic to address – the lack of radio remote TTL flash capability.

Nikon and Canon users have access to this technology thanks to 3rd party products such as Pocket Wizard – unfortunately they have not come up with a Micro Four Thirds solution – although this could be potentially possible using their Canon modules given the TTL pin system is at least physically compatible.

Canon have recently added radio wireless TTL flash to their latest dSLRs and flashes in addition to infrared TTL flash.

Nikon still only have infrared TTL flash.

Olympus uses a visible light remote TTL flash system which I personally find intrusive on the subject compared to either infrared or radio, and like infrared, it requires line of sight and relatively short working distances, which are further impacted by bright sunlit conditions.

Olympus and Panasonic have added ad hoc WiFi connectivity to their latest cameras for rapid and easy connection to smartphones which allows a device such as an Apple iPad or iPhone to remotely control the camera – even displaying the live view and allowing AF selection and shutter release.

It would seem to me that if this is possible then it should also be possible to make flash units which could be connected via ad hoc WiFi network to the camera and to other such flash units, and then Olympus and Panasonic can easily add radio wireless remote TTL flash to their system.

Well here’s hoping that this is possible and soon, because this would be fantastic for strobists everywhere who would love the Micro Four Thirds system for its portability – they just need radio TTL flash, and the option of a powerful compatible off-camera flash to allow them to push their creativity.

This would open a new market for Olympus and Panasonic.

Furthermore, using WiFi means each photographer has their own unique radio network for their flashes – no more worrying about which radio channel to use and accidentally triggering or being triggered by other photographer’s setups – particularly an issue in workshops or major events.

So what about it Olympus?

Wifi based remote TTL flash please.

 

ps. I have been told about a hack around radio TTL system that will probably work if you don’t mind taping up your flashes – see http://www.aokatec.com/AK-TTL.html which uses a similar technique as does RadioPopper.

addendum:

Seems like I am not the only one wanting this, users have started up a Facebook petition for radio TTL flash and see also blog post on LightingRumours.com.
