غطاء Canon ET-73B لعدسة Canon L Series 70-300 IS L USM

Was a bit skeptical about spending extra on a hood, but the bayonet mount clicks on so securely it feels like part of the lens. Stray light hasn't been an issue since, and the circular design doesn't block the viewfinder at all.

The stray light that used to wash out my telephoto shots is completely gone now, and the bayonet mount locks on solidly with that reassuring Canon click. Feels balanced on the 70-300 and folds down compactly enough to keep in my bag without adding bulk.

Finally found a hood that clicks on firmly and doesn't wobble like my old third-party one. The circular shape does exactly what it's supposed to, keeping glare off the front element even in harsh sidelight.
