The black Retrospective Lens Changer 2 from Think Tank allows you to carry or store two extra lenses in a soft, well-protected, inconspicuous bag. The subtle design of the bag makes it easy to tote around within a shooting venue. It's rated to hold two 70-200mm f/2.8 lenses with hoods reversed, each in its own separate compartment. With its hook & loop closure, your gear is rapidly accessed and protected by the large front flap that covers the entire bag. The underside of the flap contains a convenient, clear business card holder for easy identification of the bag or for easy distribution of your card. The back of the bag has a zippered storage pocket that contains an additional organizer pocket used for pens, batteries, memory cards or other small items. An additional accessory pocket is located on the front of one lens compartment. It's sized to hold a lens cloth, lens cap or Think Tank's optional Pixel Pocket Rocket memory card wallet. The Retrospective is carried by its top, quick grab carry handle or its breathable, cushioned canvas non-slip shoulder strap. The non-slip material integrated into the strap helps maintain its stability while in use. The bag incorporates Think Tank's Sound Silencer technology that eliminates the noise typically associated with the ripping sound produced from the touch fasteners used in traditional bags. For additional protection, the bag comes with a rain cover that can be rapidly deployed should you get caught in foul weather. Backed by Think Tank's lifetime warranty against manufacturer's defects, this bag gives you a reliable way to protect and transport your lenses in both style and comfort.
