The Lens Capsule is durable padded lens pouch, but with a bit of extra protection in the form of molded EVA caps on both ends where the lens is at its most fragile. You can set your lens down with confidence. The 12x5 in. (30x13 cm) pouch will fit a Canon/Nikon/Sony 70-200mm 2.8 with the lens hood extended, as well as a Nikon 200-500mm and other zoom lenses up to 12 inches (30 cm) in length. The secure loop at the rear of the Lens Capsule will attach to virtually any waist belt or MOLLE compatible system, as well as to the sides of many Tenba bags. The lid opens with a sturdy YKK zipper, and the interior mesh pocket holds the included Tenba microfiber lens cleaning cloth.
