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 !!!!
