That Sony lens as well as the 24-105 has some vignetting with ND filters such as Breakthrough or a little less with Freewell. Changing to 18 or 20mm will eliminate the vignetting but I would like to have the 16mm option. Kase revolution filters state the new attachment method eliminates the vignetting. Has anyone had experience with the Kase revolution magnetic filters and these two lenses? I don't have a local Kase dealer.
