DZOFilm Shim Set for Koop Rear Filters

With the help of this DZOFilm Shim Set, you can snugly mount Koop rear filters onto your Vespid or Catta Ace lenses. Eight shims are included in the set to ensure that the filter is placed snugly and doesn't move around when mounted on the camera. The shapes of the shims vary somewhat, and they come in thicknesses of 0.5, 0.3, 0.1, 0.05, 0.03, and 0.02mm.
