The JJC LH-J55C lens hood is designed for the OLYMPUS M.ZUIKO DIGITAL ED 12-50mm 1:3.5-6.3 EZ lens.

Lens hoods are primarily designed to prevent unwanted peripheral light from entering the lens by extending and shading the lens's front end. Additionally, the extendable edge offers extra protection against accidental impact.

This flower-shaped lens hood takes into account the shape and aspect ratio of the final image, allowing the hood to block excessive light from the elevated areas of the hood while allowing more light to enter the corners of the image through the lowered areas of the hood.

Moreover, this hood is reversible, remaining on the lens when not in use.
