The Digital Zoom 3 was specifically designed for digital SLR cameras like Canon's Digital Rebel with a lens attached up to 31/2". It uses Dual Foam Technology(tm) that combines closed-cell foam to provide maximum shock protection with open-cell foam for vibration dampening and a custom fit. A full-coverage top provides excellent protection by combining our Easy-Squeeze(tm) buckle for quick access with a zipper for back-up security and weather protection. The front accessory pocket has Tamrac's U.S. patented Memory & Battery Management System(tm), which uses red flags to identify available memory cards and batteries from ones that are used up. A Windowpane-Mesh(tm) pocket organizes other small accessories. A smooth nylon pocket in the lid holds lens-cleaning paper. In addition to the EasyGrip(tm) carrying handle, the Digital Zoom 3 has an adjustable, removable shoulder strap and belt loop to carry it hands-free on a belt.
