100-90mm Converter Ring for FK100 Holder
This adapter lets photographers mount the Lee Filters FK100 holder onto lenses with a 90mm outer diameter or an 86mm filter thread. It bridges the gap between the 100mm holder system and smaller front-element optics. The ring is built specifically for the FK100 system.
Limited to 90mm outer diameter lenses
The converter only fits lenses measuring 90mm across the front barrel or sporting an 86mm thread. Lenses with larger diameters cannot seat inside the ring, and smaller lenses lack the necessary contact surface. It does not adapt the holder to other filter-thread sizes.

It lets the 100mm FK100 filter holder fit onto a 90mm lens barrel so you can use 100mm filters on that lens.
