With a generous load capacity of up to 55 pounds, the RTH-1050 can support cameras up to full-sized DSLRs with massive telephoto lenses and still provide a full range of movements. The main locking knob turns easily to tighten and loosen the large 2.2 inch ball, and features an ergonomic and intuitive tension adjustment dial. Adjustable tension control ensures that a level friction is always applied to the ball to prevent losing control of the camera when repositioning. The Arca-type quick release receiver incorporates an integrated bubble level for precise horizontal alignment and is compatible with a multitude of Arca-type quick release plates, camera brackets, and other related accessories.

The generous 55 lb load capacity of the RTH-1050 enables the smooth positioning of almost any type of camera, ranging from simple compact models up to heavy camera-plus-lens combinations, with stable and secure results.

The locking knob includes an integrated tension dial that sets the minimum amount of friction on the ball. This ensures there's friction, even when the main locking knob is disengaged. This feature assures control of your camera and lens when you need to quickly unlock and reposition the ball head.

The Arca-type compatible quick release plate allows the camera and lens set to be quickly mounted. It incorporates a bubble level for precise horizontal alignment, and a +/- 25mm scale for precise quick release plate positioning. The included AQR-60 quick release plate has a D-ring 1/4"-20" mounting screw, rubber traction strips to prevent camera rotation, and security pins to prevent it from accidentally releasing from the mounting platform while being positioned.

The panning base operates independently from the main tension knob and features its own locking knob. A highly visible precision scale adds simplicity to panoramic imaging and creating repeatable results.

For exceptional strength and stability, the RTH-1050 head is constructed with aircraft-grade aluminum that can stand up to demanding use and travel and perform at the highest level. All of the control knobs are cross-hatch knurled for easy gripping.

The base of the RTH-1050 ball head features an industry-standard 3/8"-16 mounting socket machined from corrosion-resistant brass, making it compatible with virtually any tripod leg set. The socket is made from reinforced brass to resist wear for long life and reliable, secure tightening.

Q: 7. Will this fit a Nikon D7100?

A: Justin:Unless your cam weighs more than 17.6 lbs (not likely) and DOES NOT have a 1/4 -20 tripod screw hole (also not likely) in the bottom then it'll work.fine. (The screw hole is pretty standard on most (all?) DSLRs and other camera types, too.) What you might want to put on the bottom of your camera is an L-bracket so you can easily attach the cam to the tripod head since the head uses an Arca-type plate. Talk to customer service to get the right bracket for you camera.

Q: 9. What Nodal Rail will fit the RTH-1030. Is Nodal Rail from Really Right Stuff MPR-CL 5.7 or the Acratech Nodal Rail an ok fit?

A: Yes, both the RRS and the Acratech will fit the Robus RTH-1030 Triple Action Ball Head. Both of those rails are arca compatible and will work with the Robus that is also arca. Main thing you want to look for is how long the lens you are using. You want a rail that is similar to the length of your lens and camera. If the rail is much longer it may appear in the photo if you are using a wider angle lens. If the rail is too small you might not be able to place the center of the lens over the center of the tripod.

Q: 10. Why is this ball head not recommended for use on a monopod?

A: Typically ball heads offer too much motion when unlocked, which can be hard to handle when using a monopod. With only two hands to grip onto the camera or lens; monopod itself; or the head/tension release knob, using a ballhead could make it difficult to secure the lens in the correct position/orientation. Alternatively, using a monopod head limits the motion to a single axis via the primary tension knob, making it easier to adjust for tilt while not giving you any hassle with pan or roll.
