Excerpt: I usually buy the Vello branded dedicated hoods, but since it's going on a lens that retails for over half a grand, I decided to splurge. Having B&H E-rewards money to put towards it made it a no-brainer.
Excerpt: This lens hood works like most Canon lens hoods—a one quarter turn securely locks it in place for shooting and when you're ready to stow it in your bag, remove it, reverse it, and attach it to the lens "upside down". It shields the lens from stray light, preventing light from causing lens flare.
Excerpt: I've been pleased with other non-Canon brands of lens hoods, which are always less expensive than the Canon brand, but I'm happy to spend the extra money for a genuine Canon hood if there is a compelling reason.
Excerpt: I purchased this hood for a new Canon 18-135 STM lens. This hood, and all of my other hoods are from Canon. It has an excellent non-reflective surface on the inner surfaces. And it mounts precisely on my lens.
Excerpt: Great item to have attached to your lens! Two days after its arrival I was shooting waterfalls and the camera slipped. Your lens hood hit the rocks first, absorbed the shock and saved my lens, and remained intact. Also really appreciated the quick delivery time.
