The ThinkTank Glass Taxi long lens backpack carries a 400/f2.8 or 500/f4 with hood reversed, or a 300/f2.8 with camera attached. This lightly padded, compact and discreet bag is ideal for transporting your big lens on to a plane, either on your back or over the shoulder. It's also a dual-purpose bag, and can be reconfigured with the supplied divider set to hold an array of smaller lenses. There's a side pocket for a monopod, attachment points for a tripod, under-lid accessory compartments and provision for a Think Tank Pro Speed Belt to be attached to give extra support if required. Weatherproof cover and detachable shoulder strap included.
