Excerpt: Canon hood fits great. Made by Canon so I was sure it would not only fit right, but would have the flocking and right length for the lens. Read other reviews where the cheaper brands didn't fit right and had no flocking. Worth the extra money.
Excerpt: I jumped right for the Canon lens hood for my 100mm 2.8 Macro. I tried an off brand hood before for another lens before and I swore off 3rd party hoods after that because they were cheap and useless because they always pop right back off. This Canon hood is made well and stays put.
Excerpt: A good lens hood overall. I'm using it on the macro 100 f/2.8 and it serves its purpose well when shooting outdoors. Honestly, the construction could be a bit more solid (there is some torsional flexing when you put it on or take it off and you aren't grasping it where it joins the lens). The manual even advises against grasping and rotating the hood anywhere but the base to avoid warping it. That's the only reason I'm docking a star.
Excerpt: I decided to purchase the Canon lens hood over the third party manufacturers because I wanted to make sure that it would fit properly and snug. And sure enough, it does. It was definitely worth the purchase.
