The new YongNuo YN-E3-RT transmitter has only just started reaching customers hands, and already another significant improvement has been added over the original Canon transmitter through the latest V1.07. firmware update.
This update now adds the ability for the transmitter to fire when mounted on non Canon cameras, and with remote manual power control of the 600EX-RT slave flashes still available. You simply need to press the test button to transfer the M mode power setting to the flash.
[ Note – This is remote manual only though, no TTL function on non Canon cameras. ]
By far one of the most common questions asked now is which triggers will work with non Canon/Nikon mirrorless cameras, as well as having full function on Canon etc DSLR’s. This is because many people now (including many professionals) are choosing to use both DSLR’s and mirrorless cameras, for their respective advantages.
Many TTL triggers simply won’t fire if they are not connected to a dedicated DSLR with full TTL contacts on the camera hotshoe. Which is also the case with the original Canon ST-E3-RT transmitter. This is a little bit ironic, because you can actually hold the transmitter in hand (not connected to any camera) and not only remotely change manual power levels on the slave flashes, but fire them with the test fire button as well.
With the new V1.07 firmware update the YN-E3-RT can now be use with non canon cameras (provided they have standard iso hot shoe). You simply need to press the test button to transfer the M mode power setting to the flash.
This added ability to work with remote manual power control on non Canon cameras adds to the list of features the YN-E3-RT transmitter now includes over the original Canon ST-E3-RT –
- Full Group Mode with pre-2012 cameras
- Fires with Remote Manual Power Control on non Canon cameras
- Second curtain sync (in manual only)
- AF Focus Assist Light
- Slave flash charge status does not stop other flashes from firing
- USB port for firmware updates
V1.07 is available now available through links at the bottom of the page here – http://www.hkyongnuo.com/e-detail.php?ID=337
Firmware Version 1.07:
Fixed: When one of the group is set to ETTL mode, if one of the flash is not
recycled, it may make a full output flash due to incorrect light metering. Now
YN-E3-RT won’t trigger a flash in such a situation. Note: if the group is set
to M mode, a flash will be triggered no matter it is recycled or not.
Fixed: improved flash syncing with cameras after 2012.
Added: Legacy flash trigger (for non canon cameras). Now you can use YN-E3-RT
on non canon cameras with standard iso hot shoe. You need to press test the
test button to transfer the M mode parameters.
So this is quite a significant development for the many people now that would like to use mirrorless as well as their Canon DSLR’s. And really opens the Canon RT system up a step further (which Canon would no never do themselves, and are no doubt not thrilled about).
