Dedicated to the Sony E 20mm f/2.8 and E 30mm f/3.5 Macro lenses, the ALC-SH113 Lens Hood helps to minimize flare by deflecting stray light from entering the lens. The cap-style hood also provides additional protection to the lens from accidental impacts, bumps, or scratching. It is offered here as a spare or replacement for the hood originally included with the lens.
