Why should you invest in a quick-release system? Because screwing your camera or lens onto a platform with standard ¼"-20 screw is tedious and insecure. Not only is it a hassle to screw your gear onto that platform, but once installed the camera or lens is free to rotate; there's nothing to prevent it from coming loose. Why invest your money in a tripod and tripod head only to compromise your shots with an insecure connection between camera and head? Instead, adopt the Really Right Stuff quick-release system.
The Really Right Stuff quick-release system is based on the Arca-Swiss standard and has two parts: a quick-release clamp and a quick-release plate. You always need both pieces of the system. The clamp will stay on your tripod head/accessory all the time, and the plate will stay on your camera all the time. You will need to purchase a separate quick-release plate for each camera or collared, telephoto lens that you want to mount in the quick-release clamp on your tripod head.
Clamp jaws open and close in one of two ways: by twisting a knurled knob on our tried & true screw-knob clamps; or by flipping a single lever on our innovative, patented lever-release clamps. The graceful Stainless Steel S-shaped cam-locking lever provides desirable benefits over traditional screw knob clamps.
The B2 LLR II has dual mounts: center socket is countersunk on top but also threaded 3/8"-16. Mount by spinning onto an exposed threaded 3/8" post or with flat head screw from above (accept M6 or ¼"-20, not 3/8"). These clamps are appropriate for mounting on:
- Any head or platform with exposed 3/8"-16 threaded postCan drop onto a female socket tapped ¼"-20 (for any RRS head) or metric 6 (for all others; all screws sold separately)
- Any head or platform with exposed ¼"-20 threaded post - install a reducer bushing into the socket hole of the clamp
- Any head or platform with 3/8"-16 female socket - purchase our stainless steel 3/8"-16 stud
NOTE: Starting in 2012, other Really Right Stuff lever-release clamps were redesigned to automatically adjust to accept all Arca-Swiss style plates except Arca-Swiss P0 Slidefix plates and plates made by Novoflex. However the B2-LLR-II has not been updated to this new design. We recommend using the B2-LR-II if you need a more compatible lever-release style clamp. Choose a screw-knob clamp if you have Novoflex plates.
