I'm excited: The Lens Case can well carry on the belt, with the "quick release" on the tape, the upper opening is closed quickly and the lens is well cushioned in the pocket. The top cover is not waterproof, the other sides of the bag are resistant to at least water. With smaller lenses (fixed focal lengths up to 35 or 85mm) and fits even a brush and / or cloth with pure. I use the bag whenever I'm just with a camera and go for the worst-case scenario but then a special lens (Fish-eye or fixed focal length) would have it.
