Not perfect
I needed it for daytime video recordings to maintain the fps to shutter speed ratio possibly corresponding to the 1a2 ratio. I confirm that with 16/18 mm wide angles (equivalent 24/27mm full format) I can use the filter up to 2/3 of the reduction field then a vignetting or the X effect is generated. If we go to 35/50 mm at Massimo I see a not heavy vignetting. I recommend it for non-professional use and for the convenience of being able to carry it in your bag without much clutter (as an alternative to non-ND filters or 100x100). Light dominant. For my use (640iso -flog and f4-5.6 aperture with focal length > 23mm in sunlight) it is more than enough.
