Part of the modular belt system, the black Lens Changer 150 V3.0 from Think Tank Photo is a nylon pouch designed for holding long telephoto lenses up to 12.6" such as the 150-600mm f/5-6.3 and 300mm f/2.8. It can be used independently for when simply transporting the lens, or attached to an optional Think Tank belt or backpack so you can easily carry it around while shooting.
Made of nylon and polyester, the pouch features a water-repellent coating on the outside for increased durability, and comes with a rain cover in its bottom pocket that can be easily deployed in inclement conditions. Thanks to a zipper closure that opens vertically, the case allows you to quickly retrieve or store your gear from the main compartment, with an outer stretch pocket also available for holding a lens cap or other small item. A detachable shoulder strap is included with the product for comfortable transport, while an integrated grab handle allows you to carry the case with your hands when needed.
