LEE Filters Standard 95mm Adapter Ring
The adapter ring is crucial to the LEE Filters system. It screws onto the cameraís lens and the Lee Filter holder is then secured to the adapter ring by the 3 part spring loaded brass wedge.
Because the threads protrude from the adapter ring, it sits in front of the lensís front thread.
The standard adapter ring is compatible with all lens focal lengths from approximately 24-28mm (35mm SLR equivalent) and upwards.
