The Canon EW-88B Lens Hood is designed to minimize stray light and safeguard the front lens element of the TS-E 24mm f/3.5L II tilt-shift lens. It is ideal for use in various shooting environments, including outdoor locations and indoor settings. This lens hood attaches to the front of the TS-E 24mm f/3.5L II lens, effectively reducing 'flare' that occurs when light directly strikes the lens' front element. The EW-88B is specifically for the Canon TS-E 24mm II lens.
