Summary: I bought this case to protect my Canon EF 400mm f/5.6L lens. It is a bit large for the lens itself, so I have the straps as tight as possible to keep it from shaking around. It is a bit bulky for my needs but it also keeps me feeling very comfortable that it would take a lot to damage my lens. The padding is ~3/4" thick so it's a solid case. I'm able to fit my XSi body with the lens attached in here as well, though it's a tight fit length wise.
Summary: I purchased this with the Canon 300 2.8 in order to have a more easily handleable case than the supplied hardshell trunk. I then noticed that it was very hard to get the lens with the hood attached in and out. The reason is a black rubberized ring on the lens hood that makes for a lot of friction when putting the lens in and out. I put some electrician's tape on the rubberized ring and now it works like a charm.
Summary: This case is built better than many suitcases. Top of the line quality and highly functional. Minus one star for the price - not that it wasn't worth it, but it cost more than I had initially planned to spend.
Summary: I have been trying to find a way to easily carry a lot of camera equipment for quite some time. I have tried backpacks, shoulder bags, duffel bags, but none of them really worked all that well. Then I saw the Lowepro Street and Field system with completely customizable pouches, vests, belts, and accessories.
