Haida Rear Lens Adapter Ring for Canon EF Lenses

This rear filter adapter ring allows select Haida filters to be installed behind the rear element of a lens that doesn't have traditional filter threads on the front end.

Simply remove the existing rear ring from the lens, then install this precision engineered aluminum adapter ring in its place. Once the rear lens adapter ring is installed, the compatible filters can be easily installed when needed and removed when finished.

Once this rear filter adapter ring is installed it may be left in place indefinitely without affecting the operation or performance of the lens.
