Excerpt: This is an excellent lens hood that I use on the Canon 10-22mm. I thought about buying a 3rd party lens hood because they are about $ cheaper, but decided to go with the Canon because I own another Canon lens hood and I'm very happy with the quality. One main difference between the Canon lens hood and the 3rd party lens hood is that the Canon one has a black felt like material on the inside of the lens hood adjacent to the lens itself.
Excerpt: I wish I had bought this one right from the beginning. Having had good experience with Vello hood before, I got a Vello hood for my EF-S 10-22mm as well without asking questions. However, I felt that I would have broken my lens if I kept using it. The Canon one is better built, and goes on and off very smoothly.
Excerpt: This is a well built hood, just like other Canon hood. It is a very wide hood, so you might have hard time fitting your lens with hood in your camera bag. Other than that, I will highly recommend to use it at all time with your ultra wide-angle lens.
