The BH-40 recently underwent a slight re-design. Here's what's changed:
Weight reduced from 13.0z to 11.9 oz (336g) (an 8.5% reduction).
Main lock knob raised and slightly shortened so it now clears any platform diameter (previously limited to 2.7" platforms)
Main lock knob has 26 available positions (up from 6)
Main lock mechanism is more robust and durable
Up to 45% stronger lockup – new load capacity is still 18lbs but lockup will be easier to achieve. This means that more force can get you more than 18lbs, but we still only recommend 70-200mm and occasional 300mm lens limits.
Drop notches have been reduced from 2 to 1, to improve the lockup stability and smoothness of the ball joint. The single notch is now centered at the “front" when in the usual ballhead position.
New laser-engraved indicators for both lock knobs to show which direction is which, tighten or loosen.
Drag set knob has an arrow indicator showing more drag or less.
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.
The BH-40 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 perfect general-purpose ballhead. Our premise was that aesthetics needn’t play second fiddle to functionality, that operation should be intuitive and predictable, and that your investment should be rewarded with years of satisfaction.
The BH-40 offers up to 45 degrees of tilt in all directions, and up to 90-degrees in the drop-notch. Three knobs independently control the ball movement, ball friction, and an independent smooth-panning base with 2.5 degree increments.
The BH-40 PC-PRO features our patented panning clamp with screw-knob quick-release for tried and true security. When closed, screw-knob clamps can offer a higher load rating than our lever-release clamps. The PC-PRO panning clamp features laser-engraved reference marks on both the horizontal panning plane and on top of the indexing jaws.
Extensive field use has proven the utility of our innovative design. The BH-40 delivers solid performance in all weather and temperature ranges. Its low profile, precision control knobs, rugged housing, and state of the art quick-release clamps make our BH-40 the ballhead of choice for both seasoned professionals and enthusiastic amateurs.
Panning clamp with a quick-release, screw-knob style. The larger size of the PC-Pro clamp might cause clearance issues when using the drop-notch.

What else do I need?
Quick-release plates for your cameras and lenses are required to mount to the BH-40 PC-PRO. Really Right Stuff plates are custom-designed for each camera/lens model for optimum ergonomics and performance. Our quick-release clamps are compatible with all other brands of Arca-style plates, such as Wimberley, Kirk, Markins, Acratech, & Arca-Swiss. Read more about our quick-release system here and contact us if you have additional compatibility concerns.

A sturdy tripod is recommended to support the BH-40 PC-PRO ballhead. We offer support packages that pair the BH-40 PC-PRO with our Versa 2 Carbon-fiber Tripods, and can also offer custom combinations with other models. The BH-40 mounts to a tripod platform with an industry-standard 3/8"-16 stud.

You may want to also consider one of our Nodal slides, that will allow the shooter to find the optical center of their camera. Once the optical center of the camera is found a nodal slide will enable the user to shoot parallax free panoramas.
