YongNuo have officially dropped the bombshell for real this time!
Releasing the new flagship YN-E3-RT Speedlite Transmitter, and soon to follow YN-600EX-RT Flash unit!
Both directly COMPATIBLE with Canon’s RT built in TTL radio flash system, and the Canon 600EX-RT flash!!
This is real, directly from the YongNuo lead engineer –
The flagship YN-E3-RT Speedlite Transmitter will be coming first, and likely to be available around Mid to late October 2013 (as there is a National Holiday from 1st to 6th in China now). To be followed later by the YN600EX-RT flash unit.
Both will be fully compatible with Canon’s existing built in RT radio system and the Canon 600EX-RT flash unit.
The YN-E3-RT also features an AF assist light, which is something the Canon ST-E3-RT sadly lacks, and most importantly a USB port for firmware updates.
The coming YN600EX-RT flash unit will also have a USB port and AF assist light.
Unfortunately the new YN-E3-RT Speedlite Transmitter, and coming YN-600EX-RT flash units built in radio system, will not be directly compatible with the current YN-622C TTL trigger system.
Though the coming new YN-622N-TX / YN-622C-TX have also just been revealed. Likely to help appease current YN-622 owners, as those won’t actually be available until late November and December respectively.
This is a huge development, as no one really knew if direct compatibility with the Canon RT built in radio system would even be possible! YongNuo are now in a very unique position, having direct compatibility with the leading Canon RT flash system.
Phottix have also just released their own 600EX-RT style radio based flash in the Mitros +, and Pixel are expected to have a TTL radio flash at some point as well. Cactus have announced a Manual radio flash, and even Profoto have announced an “off camera flash” coming in November. But non of these are likely to be directly compatible with the Canon system, as YongNuo have now achieved.
Though this does now leave some very interesting decisions for current YongNuo flash and YN-622C owners looking to expand their system.
In the mean time the original Canon 600EX-RT flash is also at a fairly good price of $499 at the moment. They will go nicely with the YN-E3-RT transmitter, until the YongNuo flash comes later.
The advantage here is that you can have one (or more) original Canon flashes, and expand the system with less expensive YongNuo flashes and transmitter etc.
