Excerpt: Highly recommend this quality product to protect your investment. To me, it is imperative to protect my four Canon L-series lenses in my photography backpack. Protects from dust, abrasion and moisture inside my bag.
Excerpt: Protects the Canon 17-55IS with or without hood installed. Great as dust cover within photo backpack. I wouldn't use it as primary protection (it is a soft case).
Downside: looks like every other soft case by canon in the bag (confuses the wife. Could have been included with the lens.
Excerpt: I got one of these cases when I bought an L lens and purchased this one for another regular EF-S lens that didn't come with a case. I really like how it protects my L lens and so I thought it would make a nice addition to my other lenses to help protect them as well.
Excerpt: After buying it, I realized that hard case would be better. This soft lens case does not protect your lens in the event of accidental drop. Also, it's easier to carry with the hard case as you can hang it to your belt.
