The BA-106A Single Lever Ball Head from Oben is a simple ball head with one ratcheting locking knob to control all motion. The knob allows you to unlock the ball so that you can quickly orient your camera properly, retighten the knob, and return to shooting. This enables fast setup changes, and frees you to keep a finger on the trigger while you're making a quick adjustment to the head's orientation.
The ball head has a 90° notch which facilitates shooting in portrait orientation. A bull's eye bubble level ensures your camera is level on both the horizontal and vertical axes.
The included quick-release plate attaches to your camera via its standard 1/4"-20 screw. With your camera attached to the quick-release plate, it easily snaps and locks into place on the ball head, and is quickly removed by pressing the locking lever. A safety lock on the lever prevents your QR plate and camera from accidental release.
