From the Manufacturer:
Belt pouch that gives you quick access to your zoom lenses, such as the 14 - 24 f/2.8, 28 - 135, and 28 - 200, with the lens hood attached (check dimensions for lens hood compatibility). Also fits the 24-70 f/2.8 with its lens hood reversed.
Every modular component can be locked on a belt to keep bag in place on any of our camera belts.
Components can "Rotate or Lock" on the belt. To rotate, place the white plastic tang behind the belt while attaching the component. Rotating the component prevents the weight of the equipment from creating a pressure point on the hip by being stationary for an extended time. Also, moving the component to a different place on the belt allows a photographer to assume a different position such as kneeling, bracing against a wall, or lying prone without damaging gear. If locking the component in position is preferred, slide the plastic tang down into the fabric loop on the belt or rail while attaching the component. This prevents the component from sliding along the belt.
The wide mouth opening gives you quick access to your lenses. With outer stretch pocket you will have more space for a lens cap. One-hand drawstring closure secures your lenses while allowing you to focus on the next shot. Includes a seam sealed rain cover which is stored in a zippered pocket at the bottom of the pouch. When not using the rain cover, this pocket can be used to store a small accessory.
Attaches to all Think Tank Photo belts and belt packs.
