Though it doesn't look like a camera bag, the Velocity 7x - Photo Sling Pack is a unique, ultra-functional pack that carries like a backpack, but swings around to the front for quick access to an SLR with a 6" lens attached and a couple additional lenses.  Inside the main compartment, the camera with lens attached is suspended on two vertical, foam-padded dividers.  The secure, zippered Quick Flip Top opens away from the body for fast and convenient access to camera gear.  A well-padded sling strap comfortably distributes the weight, but need not be removed to quickly access photo equipment.  A Tuck-A-Way™ waist belt allows the pack to be used while hiking, biking or doing other activities.  The front pocket has organizer pockets inside to keep a mobile phone, PDA or photo accessories within easy reach.  It also features Tamrac's U.S.-patented Memory & Battery Management System™ that uses red flags to identify available memory cards and batteries from ones that are used up.  A pocket inside the lid stores filters and lens caps.  This pack is also customizable with Tamrac's Modular Accessory System™ components.
