The Pro Digital Zoom 9 is ideal for carrying a pro digital SLR with a 200mm zoom lens attached. Dual Foam Technology™ provides protection and a custom fit to pro digital SLRs. The front pocket features Tamrac's U.S. patented Memory & Battery Management System™, which uses red flags to identify available memory cards and batteries. A smooth nylon accessory pocket in lid holds lens-cleaning paper. The Pro Digital Zoom 9 is compatible with Tamrac’s Modular Accessory System™ (M.A.S.™) and Strap Accessory System™ (S.A.S.™) products. A belt loop in back quickly converts this Zoom Pak from a shoulder bag to a belt holster. Can also be carried by the EasyGrip™ carrying handle or padded BioCurve™ shoulder strap.
