Gimbal heads are designed mainly for long, heavy telephoto lenses, and are often used for wildlife or sports photography. Their primary feature is the ability to balance the camera and lens within the tripod head and use tension controls to simulate a "weightlessness".
Illustration of a simple three-axis gimbal set; the center ring can be vertically fixed. A gimbal is a pivoted support that permits rotation of an object about an axis. A set of three gimbals, one mounted on the other with orthogonal pivot axes, may be used to allow an object mounted on the innermost gimbal to remain independent of the rotation of its support (e.g. vertical in the first ...
Other head types include the gimbal, fluid, gear, alt-azimuth, and equatorial heads. Fluid heads and gear heads move very smoothly, avoiding the jerkiness caused by the stick-slip effect found in other types of tripod heads. Gimbal heads are single-axis heads used in order to allow a balanced movement for camera and lenses. This proves useful ...

Gimbal lock is the loss of one degree of freedom in a multi-dimensional mechanism at certain alignments of the axes. In a three-dimensional three-gimbal mechanism, gimbal lock occurs when the axes of two of the gimbals are driven into a parallel configuration, "locking" the system into rotation in a degenerate two-dimensional space.
