Kase Revolution Inlaid Magnetic Adapter Rings are used in conjunction with the Kase Revolution Entry ND Kit, Kase Revolution Professional ND Kit, Kase Revolution Mega Set, and Kase Revolution Plus Master Kit.
This adapter ring fits directly inside your lens's front threads, allowing magnetic filters to attach closer to the lens to reduce vignetting, and allows your existing lens caps and lens hoods to be used.
Please note that these adapter rings are only suitable for use with the same size kit you have bought, i.e. if you have a 77mm kit, only a 77mm inlaid ring will work with the kit.
If you need to "level up" from a smaller lens size with any step-up adapter rings, please purchase the Kase Magnetic Step-Up Adapter Rings.
