I wonder will it work with YN 622c?
I guess some people want to feel theyre gettibg something special when buying an oem flash. I dont see any reasonable reason with such wonderful 3rd prty flashes from godox yongnuo shanny abd now pixel. Just dont see it. Especially this crap. Underpowered overpriced. 3.5 secobds recharge for such a weak flash. Ripoff flash.
Hi Nevel,
Actually I think these look like great flashes. Particularly for anyone after something smaller, but still with very usable power.
The 3.5 second figure is with Alkaline batteries, with NiMH that should be significantly faster.
The previous 430EX II are only around half a stop less powerful, and the 430EX III-RT appear to be the same. So that’s not a great loss especially taking into account the considerably smaller size.
I certainly wouldn’t have expected Canon to provide a full radio Master function, so that’s a great win for common sense for once.
Third party flashes may make more sense for radio slaves, it just depends on what your needs are.
I can’t think of a single WONDERFUL 3rd-party flash: the all have issues. This flash is going to be awesome and it’s far, far from “crap”–Including a master mode is huge.
I don’t see the point of denigrating something simple because it doesn’t fit a particular budget.
People buy knock-offs because they’re cheaper: that’s it.
Not exactly a TTL flash, though I think the V850 are pretty awesome for a manual flash (despite few battery hiccups).
Because they are better made. Within a few weeks of use my yn500 stopped working, if it had been OEM I could have complained and got a replacement. I tried for weeks with yongnuo but to no avail. They might be better now or I got a dodgy unit, but why would I risk doing that again?
I think that it will be a great flash trigger. Especially for those who don’t like the canon St e3 rt missing a focus assist. Plus the price of this flash and the St e3 rt are similar.
What a wonderful flash for on-cam grabshots and travel etc etc…. Hopefully Yongnuo is paying close attention to this gorgous little thing.
These are actually pretty cool. Next thing I’d love to see is an extra small 2xAA RT slave flash for under $200.
I agree. A 270 rt would be amazing!
Repeating myself from the first post, I wonder will it work with YN 622c?
So excited for these — we have three on pre order. I view it as an ST-E3 with a built in AF assist light and … a flash to boot.
The PDF manual is now available for viewing on the Canon USA site and the wireless flash interface is a version 2 effort with better panel organization. Yay!
Thanks tomK.
It looks like they have managed to put all 5 Groups on the display at once in GR group mode. If that is right it looks to be a pretty decent Master interface.
Exactly — amazing that it’s so small at the same time. So excited to put them into the fleet.
Hi,
Question: Can 430 III be a master and control YN600ex-rt too? If so, it would be nice since i have canon 600ex-rt and several YN600ex-rt
Thanks.
Hi Andy,
Yes the 430EX III-RT can be a master. I don’t have one yet to test this, though it should work as a transmitter to the YN600EX-RT as well as Canon RT flashes.
