UPC: 609465151519 The EW-73B is a perfect replacement for the original Canon lens hood model. Dedicated lens hoods are designed to match the specific focal length of the lens it was designed for. The addition of lens hoods can help prevent flares (circles of light) in pictures created from nearby light sources for better quality photos. Lens hoods also have the added benefit of providing protection to your lenses and filters from accidental bumps, scratches, and other forms of damage. They are one of the most important (yet overlooked) accessories for improving the quality of photos. Features: Secure bayonet locking mechanism. Designed for a tight and secure fit. No wobbling or cross-threading. Reduces extraneous light sources for better quality photos. Made of high impact plastic for an extremely solid and lightweight feel. Handy reversible design allows you to attach the hood in reverse for easy storage in your bag. Compatible with Canon 18-135mm EF-S f/3.5-5.6 IS, 17-85mm EF-S f/4.5-5.6 IS USM Lenses.
