The Super Telephoto Lens pack allows a photographer shooting with a long telephoto lens to carry the equipment and accessories needed without having to carry an oversized, cumbersome pack. This specialized professional pack holds a long telephoto lens up to 600mm (18 inches) attached to a pro DLSR with a grip, but is still narrow and compact. It also meets most US airline carry-on size limitations of 22 in x 14 in x 9 in.
