Zoom - manually or/and automatically

It seems I can set the zoom - focal length - manually for an off camera flash. Sometimes, I believe, the ON CAMERA flash is zooming automatically - as ff there was no tranceiver in between. Is this at all possible or do I remember incorrectly? How should I set thing to make the ato zoom work on the TTL pass through flash, please?


  • Forgot TTL pass through
  • Automatic zoom for off-camera flash set in Group A,B,C and D is not available.

    Only Manual zoom is available for off-camera flash.

    Automatic zoom for on-camera flash (on top of V6 II) is possible by setting the on-camera flash mode to TTL - hold down V6 II's Menu button for 2 seconds. You will see a TTL icon below the battery icon.

    Manual zoom is available when you set on-camera flash mode to manual control, TTL icon will not show below the battery icon, but the channel number instead.

    Hope this helps.
