The Digital Juice Orbit Dolly/T-Bar Handle/Wheel Sets (2) Kit from B&H Photo is a complete efficient camera tracking device that allows you to achieve 360° radial as well as straight line dolly motion for a camera weighing up to 300 lb (136kg). In addition to the dolly, this kit includes two sets of casters (5" and 8") and a T-bar handle.
You can use the dolly with or without a tripod in tabletop, normal, or wide mode thus achieving wide flexibility. Rotation around a subject while keeping the camera focused on the subject is possible, thus eliminating the need for special straight and curved tracks for dolly movement.
Integrated into the dolly are 3" (76mm) polyurethane casters that ensure smooth mobility under maximum load conditions. Or use the included 5" casters or 8" pneumatic wheels. You can easily adjust the dolly legs to facilitate transportation. Constructed from a 0.5" aluminum plate, the Orbit Dolly is lightweight (22 lb / 9.9kg) and durable.
The included T-bar handle reduces vibration by supporting dual anchor point attachment--especially useful for use with telephoto lenses.
A matte black powder coating on the body of the dolly protects it from environmental conditions and also prevents unwanted reflections.
