Q: 3. Has anyone here used this adapter ring with the Lee 100mm foundation kit as wide as 16mm? I currently use the Format HiTech 100mm holder on my canon 16-35 II and it vignettes severely (not really a vignette actually the filter holder blocks the corners of the frame). Will the lee system allow me to shoot 16mm without appearing in the frame? A Lee rep. told me it would but I just want to be sure before I invest in a new system. Thank you.

I realize the Lee Seven5 system might work better with the Fuji X cameras, but I already have a Lee filter system for my full-sized DSLR, so was hoping I could avoiding duplicating equipment...Greg
