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.
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.
