The injection molded waterproof cases are constructed of ultra high-strength polypropylene copolymer resin and feature a gasketed, waterproof, submersible design (IP67) that is resistant to corrosion and impact damage. Its continuous molded-in hinge, patented trigger release latch system, comfortable, snap-down rubber over-molded cushion grip handle, secure stacking and automatic ambient pressure equalization valve all contribute to its military grade design. Perfect companion case for the professional photographer. This case will hold six lenses such as the Canon Cinema Prime Lenses or Schneider Kreunznach Xenon FF prime lenses. Each lens slot has a diameter of 125mm and the base depth of each lens slot is a total of 120mm. The useable lid depth is 35mm creating a maximum length of 125mm per lens. There are two removable foam discs provided to change the internal base lens height to 97mm instead of the 120mm when needed. This case is the maximum approved size for airline carry on travel.
