The Tenba Shootout Sling bag is unique in its ability to be converted from a “quick-draw” shooting bag to a long lens bag configuration, offering incredible versatility, especially to sports and wildlife/outdoor photographers. The Sling bag is carried on the back with a single, contoured and padded cross-chest strap rather than two shoulder straps. This design allows it to be instantly swung around in front of the photographer, providing immediate access to a primary camera with mounted lens, for fast shooting right out of the bag. Movable padded walls within the bag allow the “quick-draw” compartment to be fitted precisely to the main camera/lens combination, and also create additional spaces for extra bodies, lenses and accessories. These walls can be completely removed, turning the Sling into a vertically-oriented long lens bag. In this configuration, a pro D/SLR with mounted telephoto—up to 300mm 2.8 (also Canon 400mm 4.0 DO) for the medium Sling (depending on specific equipment used)—is loaded straight down through the bag via the large top door. Many requests from professional photographers were incorporated into Shootout Sling, such as the use of durable, water-resistant nylon instead of the more common polyester for the exterior, weather-sealed YKK zippers on all outside openings, monopod straps, protective rubber bottom treads, and more. The Tenba Sling also provides a full-access back panel that can be opened to fully expose the interior for setup, loading and cleaning. Other features include Tenba’s fast-deploying WeatherWrap rain cover, a strap front-mounted phone/audio pouch, auxiliary security strap, and a variety of accessory pockets and compartments. Despite the special materials and arsenal of features, the Sling weighs in at only 35-46 ounces, depending on configuration.
