The L611 Compact Long Lens Case 600 from Kinesis provides a secure transport and storage solution for some telephoto and telephoto zoom lenses with a DSLR body and the lens's hood in the shooting position. Compatible lens and camera combinations include a Nikon or Canon 500 f/4 or Nikon 200-400 f/4 lens with an attached quick release plate and a full-sized DSLR along with the lens's hood in the shooting position and with its leatherette cap in place; a Canon 500 f/4 lens with an attached quick release plate, a 1.4x teleconverter, and a full-sized DSLR along with the lens's hood in the shooting position; a Canon 800 f/5.6 lens with a full-sized DSLR along with the lens's hood in the stowed position, plus a Don Zeck lens cap; a 300 f/2.8 lens with a 1.4x teleconverter, and a full-sized DSLR along with the lens's hood in the shooting position and with its leatherette cap in place; and a Canon 600 f/4 lens with its hood in the shooting position, along with a Don Zeck lens cap.

This Kinesis lens case is compatible with both the Kinesis TwinBuckle Attachment System and the Kinesis Attachment Tab System (KATS) for ease of use with Kinesis pouches, harnesses, or straps. The clamshell-style lid features a touch-tab closure for quickly removing and stowing a lens and camera while shooting. In instances between shots where quickly withdrawing a lens and camera is less of a priority than making sure that they sit securely within the pouch, the lid can also be closed using its water-repellent zipper.

The exterior consists of 500 denier nylon for water-resistance. A Kinesis Y515 Heavy-Duty Padded Shoulder Strap is included to allow the case to be carried over one shoulder. Also included is a Kinesis A257 Body Pouch which can accommodate one pro-sized DSLR and can be attached to the lens case.
