The Cinema Vista Nikon F Mount and Shim Kit from Tokina enables users to convert their Tokina Cinema Vista prime or zoom lens to Nikon F Mount. Also compatible with the Tokina Cinema ATX 100mm macro prime, this set includes the mount, five shims, screws, and a rear lens cap. As the flange-focal distance can vary among camera types, it can be necessary to make adjustments when switching between lens mounts or camera models. To perform this adjustment this kit provides shims in multiple thicknesses.
