The 100mm Slipover Foundation Kit from Lee is a unique item designed to attach directly to the outside of lenses measuring 100mm in diameter. Most 95mm thread "filter size" lenses measure 100mm on the outside of the barrel. For smaller lenses, an optional adapter ring is required.
This filter holder is particularly useful with the 72mm and 90mm Schneider Super-Angulon "XL" lenses, the Schneider 150mm Super-Symmar and certain Fuji lenses (with 95mm filter size) for the GX-680 System.
This holder will accept two resin filters measuring 4" (100mm) x 2mm thick. It also accepts 4 x 6" (100 x 150mm) filters (x 2mm thick).
Note! This holder is specific to clamping lenses that measure 100mm outside diameter. It does not need an adapter ring, nor is there any additional adapter ring available for it. However - Fuji item #FUAR100 does a reasonable job of adapting this item to fit 82mm.
