The SLR Camera Case from Aquapac is designed to fit most consumer SLRs with standard lenses up to 4 (10.2cm) including all bodies which use an APS/DX sensor, and some smaller bodies with full sensor. The tough thermoplastic polyurethane casing protects your gear from dust, dirt and that most evil of contaminants - sand. The casing contains a permanently attached tough acrylic lens that will work even underwater. Even if you aren't swimming but drop the case in water, it will float; but don't worry since the seams are all welded for additional protection. The Aquaclip sealing mechanism is easy to use and opens and closes the bag via dual twist levers. Aquapac has included five desiccant sachets that will help minimize the harmful effects of humidity. The included shoulder strap makes it even more portable.
