A Really Right Stuff ballhead is the best choice for all general photography, and will give you fast and accurate control and solid support of your camera or lens. Aiming and horizon leveling can be accomplished as one instinctive motion, and rigid lockup takes just a quick twist of one control. As a result, our ballheads are faster to use and inherently more stable than 3-axis “pan-tilt" tripod heads. Since the ballhead profile is smaller and lacks the protruding handles, they are also much easier to carry and pack.
These are no-nonsense heads with robust capacity, offering minimal weight and elegant simplicity. They excel as ground-level macro tools, but also as super light heads for backpacking, travel, and table top use.
The T-lever on the BH-25 is longer on one end to help you lock the ball down solidly. It is spring loaded; simply pull it out to reposition the lever to allow it to clear wider tripod platforms. The BH-25 ballhead has a beefy T-lever to lock ball articulation and the panning base. "
