At just 2.9" in height with a 1.2" ball, the BH-30 Ball Head with Mini Screw-Knob Clamp from Really Right Stuff is a great support solution in a small form factor. With a load capacity of 15 lb, the BH-30 is a great match for pro cameras with lenses up to 70-200mm and mirrorless and bridge cameras alike. The head features an oversized spring-loaded locking T-lever that can be conveniently pulled out and repositioned in 60-degree increments. The panning base has a separate lock and is laser-engraved in 2.5-degree increments from 0-360 degrees for accurate repeatability.
