Excerpt: I use this case (and the other ones of the same type) to give some protection for my lenses when I am storing them in my travel pack and hiking pack when I go on vacation. It keeps the bulk to a minimum but still offers a decent level of protection.
Excerpt: I used to keep my Canon 50mm f1.4 lens in a bubble plastic wrap that came out of the box of the lens. It is really a shame that Canon only sends these cases with L series lenses. I bought this case and threw away the bubble plastic wrap finally. It is what you get when you buy a L series lens.
