The Lee 39mm Adapter Ring for RF75 Filter Holder System features a sturdy design that fits on to either the lens or filter holder. The holder itself effortlessly clips in to the ring making the full system ready for use in seconds. The quick release, spring-loaded attachment mechanism makes using this system a breeze.
The wide angle rings for the RF75 are manufactured so that the filter is as close to the lens as possible. In this way, unwanted vignetting can be avoided.
