This camera bag is a favorite all over the world with serious photographers, the 335 has undergone a substantial re-design. The main compartment now has four extra "full-depth" pockets. The single, top opening was retained, but has now been re-profiled, so that it"s possible for the zip panels to lie out of the way behind the inside pockets, to form the Billingham TukTop. In use the zipper can remain open and equipment kept out of sight and protected with the main flap. The simple straight zipper path allows a long, trouble-free life. The adjustable Delta shoulder sling comes complete with a leather and neoprene SP15 shoulder pad for a comfortable "hands free" carry. An 8-15 and 9-18 Superflex are included.
