From the Manufacturer:
Belt pouch that accommodates standard zoom lenses, small primes and teleconverters, both with and without caps.
Soft inner lining on this pouch allows you to drop-in your lens or teleconverter without the need for using caps. Unique pull closure keeps your lens securely in place with lens hood in shooting position, even when it sticks above the rim of bag (check dimensions for lens hood compatibility).
The Lens Drop accommodates standard telephoto zoom lenses, small lenses, teleconverters. The belt pouch has a cinch top that securely keeps your lens in place. With a soft inner lining, the Lens Drop protects lens elements, even when not using caps. 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.
Every modular component has a rain cover included in the bottom zippered pocket.
Attaches to all Think Tank Photo belts and belt packs.
