JJC ES73B Bayonet Lens Hood Compatible with Canon RF 45mm F1.2 STM Lens, Reversible Shade Replaces ES 73B

COMPATIBILITY: This lens hood is only suitable for Canon RF 45mm f/1.2 STM lens. Replacement for Canon ES-73B lens hood. PROTECT THE LENS: With the extended lens end, you will also benefit from extra protection from accidental physical knocks and scrapes. BLOCKS STRAY LIGHT: JJC bayonet lens hood is designed to prevent unwanted stray light from entering the lens by extending and shading the end of the lens. REDUCE LENS FLARE: Non-glare matte finish on the inside further prevents or limits 'flare' caused by light shining directly on the lens' front element. No vignetting will show with the hood on. SUPPORT REVERSE INSTALLATION: The hood can be reversed and fitted to the lens to save space in storage. And the hood allows putting on a Ф67mm filter and a Ф67mm lens cap.
