Calumet / Lee Filters Resin Filter Holder Adapter 72mm

Adapter Rings are the first stage of the LEE Filters System. Use Adapter Rings to attach holders and hoods to lenses. With a different ring for each sized lens, you can use the same filters, filter holder and hoods on any lens in your system. Each adapter ring screws to the lens, enabling the filter holder to be clipped into place using a smooth, quick release spring-loaded mechanism.
