Dedicated to the Sony FE 28-70mm f/2 GM lens, the ALC-SH182 Lens Hood helps to minimize flare by deflecting stray light from entering the lens. The hood also provides additional protection to the lens from accidental impacts, bumps, or scratching. This hood also incorporates a filter adjustment window which benefits the use of rotating filter types, such as polarizers and variable NDs, without needing to remove the hood.
