The Haida Rear Lens ND Filter Kit is designed for the Sony FE 12-24mm F4 G wide-angle zoom lens. It includes four neutral density filters—ND0.9, ND1.2, ND1.8, and ND3.0—that reduce incoming light by 3, 4, 6, and 10 stops, respectively. The rear-mount design provides an alternative to front-mounted filters for this wide-angle lens.

Constructed from optical glass, the filters support long-exposure photography, motion blur effects, and wider-aperture shooting in bright conditions. The kit includes a dedicated adapter ring for installation. It is suitable for landscape photographers, architectural photographers, and videographers who need exposure control with a compatible Sony lens.
