as the title states, I can't figure how to zoom my flash head wider than 35mm. I use them off camera with Yonguo 602's and while they are in slave mode & in Manuel. I can zoom the head from 35mm to 105mm. I can also get it to go to 16mm by pulling out the wide angle diffuser, but when I push it back in, it goes back to 35mm............I am sure I am missing something very obvious and simple, and POTN should be able to solve this issue for me, thanks to all in advance, I appreciate it !!!!

That is weird. When you pull the wide panel out, the zoom should indicate 14mm, not 16mm. And if you are zooming manually, it should go from 24mm to 105mm. I've never heard of what you're experiencing.

What happens if you change the setting of C.Fn-09 on your flash? Not sure if it will make a difference but it might be worth checking.

Yes you are right, it does say 14mm, not 16mm when the wide angle diffuser is pulled out, I typed incorrectly.

I just tried c.Fn-09 enabled & disabled, and I have the same issue.

When the flash is on-camera, and can zoom it from 24mm to 105mm. Off-camera only 35 to 105mm...............th​anks for you input PacAce

Strange... I'm have my 580EX II in Slave Ch 1 and I can get it to MZoom 24mm off-camera with no problems. I thought maybe the position of your flash head might be a reason, but I tried different position and is I can get it to MZoom 24mm. I'll keep playing with it to see if I can duplicate the problem.

35mm is the default zoom setting. Do you see a 'M' indicator right next to Zoom on the screen? Push the
'ZOOM' button once. When it's flashing, turn the dial clockwise. It will be in Manual zoom mode and start with 24mm.
