RRS : BC-18 Micro Ball
(No reviews yet) Write a Review


The BC-18 Micro Ball is the perfect travel companion weighing in at only 3.7 ounces and a mere 1.8 inches tall, the BC-18 makes the cut in any gear bag. The new BC-18 Micro Ball offers near ballhead functionality* in an ultra-compact profile. Featuring a unique lever lock to control the ball joint, the lever lock is a very intuitive process with positive visual and tactile feedback versus a traditional screw-knob. The contoured locking lever also enables a significantly smaller footprint versus a traditional screw-style control knob. Featuring a male threaded 1/4"-20 mounting post, the BC-18 can mount to nearly any photographic accessory that features an industry standard 1/4"-20 threaded socket, or any 3/8"-16 socket with the use of a threaded reducer bushing. The BC-18's built-in Really Right Stuff (and 1.5") compatible screw-knob style quick-release clamp accepts any Really Right Stuff mounting plate or rail and maintains a slim overall profile.
