Yongnuo YN568EX-II Master Mode

The Yongnuo YN568EX-II has the ability to control up to 3 groups of remote (slave) speedlites, being Groups A, B & C in either ETTL, Manual or Multi Mode.

Unlike the regular on-camera operation, manual mode isn’t always intuitive and the Yongnuo manual is not exactly great either.  With this in mind I’ve put together a sequence of steps that should help you understand it’s functions.

After pressing OK the display would look like this:

Everything we change from here is based on pressing the zoom button to select what we need to change.  This may not be as intuitive to some people, but once in master mode the zoom button cycles between

• The zoom position
• The Channel selector (Channels 1,2,3,4)
• The Group & Ratio selection (A:B, A:B:C) (ETTL mode) or group power (manual mode)
• Master fire (on/off)

To set the Channel
Press the zoom button (repeat if required) until the Ch is flashing then press the left or right button to change the channel (possible channels are 1,2,3 & 4), then press OK to confirm. The purpose of channels is so that multiple photographers can be using flash in the same location without triggering each other’s flash setup.

To Set The ETTL Ratio
Press the zoom button (repeat if required) until [RATIO] is flashing, then use the left / right keys to select the required ratio type.  Possible types are A:B and A:B:C.  Use A:B if you want to control only 1 or 2 groups and A:B:C if you want to control 3.  Note that more than one remote flash unit can be a member of each group with all members of the same group using identical settings.

YN568EX-II A:B Ratio.  A will emit twice as much as B (2-1)

YN568EX-II A:B Ratio. In this example Group A will emit twice as much as Group B (2-1)

A:B Ratio: Press the OK button (repeat if required) until the A:B is flashing, then using the left and right keys to set the A:B ratio. The values are displayed at the bottom right of the LCD. Press Ok to accept.

C Ratio: Press the OK button  (repeat if required) so the C ratio is flashing then use the left and right keys to change the value.  Press Ok to accept.

Manual Settings Per Group
In manual mode each group is set to a specific value manually!  Press the zoom button until ratio is flashing, then left or right to select A:B or A:B:C control, then press OK to select.
To set the individual groups press the OK button until the required group is flashing on the main screen (A, B or C) then press the up/down/left/right keys to set the power value and press Ok to select.

Disable Master Flash
It’s not possible to totally disable the master flash because the master uses visible light to communicate with the remote flashes and it’s recommended that the head be turned away from the subject where possible.  However, the main flash can be dramatically reduced by selecting the master flash and setting it to off.  To do this press the zoom button until the master flash icon is flashing, then use the left or right buttons to select ‘oF’ or ‘on’.  Note the master flash icon will turn off when disabled.

Exit Master Mode
To exit master mode hold the zoom button for 2 seconds until the [MASTER] indicator flashes then use the left button to select ‘oF’, then press OK.

    Will the Yongnuo YN568EX-II work with the GH4 in TTL?

    Just found your site as a result of a google search. Nice job keep up the good work. I will be a regular.

    Thank you

    Kent

      Unfortunately not. When you mount the YN568EX-II on a GH4 it outputs a fixed flash value every time.

      For TTL on the GH4 you need to be looking at the Olympus / Panasonic range, Metz or the Nissin i40 (see my Nissin i40 review for more info).

      It can fire the YN560-III if the 560 is in dumb optical slave mode. In this mode you will need to manual set the exposure on the 560 and this cannot be controlled via the 568EXII. The 560-III does not have TTL mode.

    David,

    many thanks for posting these help guides. I decided to take the plunge with the YN568, I couldn’t really justify the price for the comparable Canon unit. If I may trouble you for one question ? I am using it with a Canon 7D Mk1 and all seems to be fine, however when I go into the cameras Remote Flash setup menu it states the flash isn’t recognized or incorrect power. Any suggestions would be much appreciated

    Regards
    Paul

      Paul, I don’t think the 7D mk1 is compatible for in-camera menus, but I’d be happy to be proved wrong. Unfortunately I can’t check it personally since I sold my 7D some time ago.
