I was wondering if anyone has managed to fit a screw on dual element achromatic diopter to an FX1/Z1 on a Phenom housing.....I know the flip filters would need to be removed....

Some of the extreme macro video footage I have shot with a +3 standard diopter shows spherical abberations and I know achromatic diopters eliminate that. For $375 for a Schneider achromatic dual element diopter, they better!
