Excerpt: This is the only lens hood that fits the 18-55mm lens properly. All the other aftermarket lens hoods are either made from really soft plastic or they don't fit the right way. I bought this HB-45 lens hood and noticed how much stiffer the plastic is. There is hardly and flex to it. This hood slips on and off very easy. With my old hood the plastic would distort when I pushed the two buttons to remove it. This resulted in the hood getting stuck.
Pros: Durable, Easy To Use, Fits like it should, Reliable
Summary: If you want to block out any stray light, this does the trick. It's not as "pro" looking as a petal shaped hood, but it fits real nice (since it's made specifically for the lense I have it on). I do a lot of photos of my kids in the yard and we have no tree cover, so the sun has always been an issue that annoyed me until now!
