This Haida Rear Lens ND Filter Kit includes four ND filters plus a dedicated rear lens adapter ring. The adapter ring is compatible with the Sony FE 12-24mm f/2.8 GM and 14mm f/1.8 GM lenses. It's made of robust aerospace aluminum and is highly lightweight. It attaches to the rear of the lens, and the included filters interchangeably mount directly into it and reduce the amount of light without compromising color accuracy.

The filters feature K9 optical glass and Nano coating that prevents reflections while protecting from scratches and repelling water. This rear lens kit enables you to use ND filters with the Sony lenses without the use of filter holders on the front of the lens. A screwdriver and screws are included for securing the adapter ring to the back of the lens. Three screws are already set in the adapter ring. (Certain lens parts are required to be removed from the rear of the lens before attaching the adapter ring.)
