The Arca-Swiss Svilt Quick Release Adapter is an "L" shaped quick release plate that fits into any Arca Swiss-type quick release system, and provides a Flip-Lock adapter at 90° to the head's quick release.
The advantage of this plate is to allow the use of the ballhead in the 90° vertical orientation position, limiting the ball movement to tilt operation only. This greatly simplifies the control of long, heavy telephoto lenses and is heartily recommended.
Note: Requires camera mounting plate.
