Really Right Stuff BH-55 Ball Head, Screw-Knob Panning Clamp, 50 lb Capacity

The BH-55 is the culmination of years of iterative development based on first-hand experience and abundant input from seasoned professionals and enthusiasts. Our goal was to build the best ball head out there. Our premise was that aesthetics didn't have to suffer for the sake of functionality - that operation should be intuitive and predictable.We also had you, the photographer, in mind in that we believe that your investment should be rewarded with years of satisfaction. The BH-55 offers up to 45 degrees of tilt in all directions, and up to 90-degrees in the two drop-notches. The knurled main lock knob independently controls the tension of the main ball joint.The midsize knurled knob features independent control of the panning base, which features laser engraved degree markers every 2.5 degrees. The smaller spade knob works in concert with the main lock knob to set a minimum amount of resistance on the ball joint at all times, independent of the main lock knob being fully loosened or not.Extensive field use has proven the utility of our innovative design. The BH-55 delivers solid performance in all weather and temperature ranges. Its low profile, precision control knobs, and rugged housing make our BH-55 the Ball Head of choice for both seasoned professionals and enthusiastic amateurs.
