The Adventure Zoom 4 holds a digital or film SLR with a zoom lens up to 3 1/2" long attached and ready for action. The front pocket features Tamrac's US-patented Memory & Battery Management System, which uses red flags to identify fresh memory cards and batteries from ones that are used up. An EasyGrip carrying handle, adjustable, removable shoulder strap and belt loop in back provide convenient carrying options. An additional Windowpane-Mesh pocket organizes other small accessories. A smooth nylon pocket in the lid holds lens-cleaning paper. Add Tamrac accessories to the Modular Accessory System (M.A.S ) and Strap Accessory System (S.A.S ) attachment slots to customize the bag.
