Previous Firmware Versions -
Fixed: couldn’t set fec of group b/d via camera menu.
Fixed: update limit of flash number in Multi mode.
Fixed: disable HSS in multi mode
Added: P.FN: legacy trigger mode. When it’s set, YN-E3-RT won’t detect ettl
input so that it can be used on Fuji hotshoes.
Added: P.FN: Free Mask Group. This setting is used with GR/*. Free mask will
be on/off when you hold GR/* button for a few seconds. When Free mask is on,
groups not in this setting won’t fire. So you can take a photo with background
flashes only quickly.
Fixed: correct ettl2/gr exposure for 1D-X.
Fixed: improved light metering for cameras after 2012.
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.
Added: allows the firmware version to be checked in menu 4.
Added: compatibility with 5D MKIII and 6D cameras.
