The Digital Zoom 4 was designed for digital SLR cameras with a lens attached up to 4-1/4 inch. It is ideal for Canon's Digital Rebel, EOS 10D, and Nikon's D70 with the 18-70mm lens attached. Dual Foam Technology provides protection and a custom fit for digital SLR cameras. The front pocket features Tamrac's exclusive Memory & Battery Management System (patent pending), which uses red flags to identify fresh memory cards and batteries from ones that are used up. An additional Windowpane-Mesh pocket organizes other small accessories. A smooth nylon pocket in the lid holds lens-cleaning paper. Two zippered side pockets hold additional accessories such as a cell phone or PC card. Belt loops, an EasyGrip carrying handle, and shoulder strap provide convenient carrying options. Add Tamrac accessories to the Strap Accessory System (S.A.S) attachment slots to customize the bag.
