Irix Cine Shim Kit

Back focus drifts. A lens that was on the money at the rental house comes back off after a season of travel, and on a cine prime the fix is a shim behind the mount, not a menu item. This kit is the set of shims for doing that on Irix Cine glass.

Eight discs in three thicknesses: three at 0.025 mm, three at 0.05 mm and two at 0.1 mm, which stack to cover the range a working lens actually needs. The set fits every focal length in the Irix Cine line, so one kit covers a full case.
