Steadicam is a brand of camera stabilizer mounts for motion picture cameras invented by Garrett Brown and introduced in 1975 by Cinema Products Corporation. The Steadicam brand was acquired by Tiffen in 2000.[1] It was designed to isolate the camera from the camera operator's movement, keeping the camera motion separate and controllable by a skilled operator.

Before the camera stabilizing system, a director had a number of choices for moving (or "tracking") shots:
While these cinematic techniques are still common, smooth and steady tracking shots with lighter weight camera systems was enabled with the creation of the Steadicam in 1975 by inventor and cameraman Garrett Brown.[2] After completing the first working prototype, which was called the "Brown Stabilizer", Brown created a ten-minute demo reel of the new cinematography techniques enabled by the Steadicam and was shown to numerous directors, including Stanley Kubrick and John G. Avildsen. The Steadicam was subsequently licensed to and manufactured by Cinema Products Corporation, which later diversified the brand into a consumer line of Steadicams for light weight DV cameras.

 First use of Steadicam | |
 Bound For Glory Steadicam Shot |
The Steadicam was first used in the Best Picture–nominated Woody Guthrie biopic Bound for Glory (1976).[3] Cinematographer Haskell Wexler had Brown begin a shot on a fully elevated platform crane which jibbed down, and when it reached the ground, Brown stepped off and walked the camera through the set.
Steadicams were then used extensively for chase scenes on the streets of New York City in Marathon Man (1976), which was released two months before Bound for Glory. The Steadicam's third picture was Avildsen's Best Picture–winning Rocky in 1976, where it was an integral part of the film's Philadelphia street jogging/training sequences and the run up the Art Museum's flight of stairs. In many fight scenes a Steadicam was visible ringside, as well as during some wide shots of the final fight. Rocky was also released before Bound for Glory. Garrett Brown was the Steadicam operator on all three films.[3]
The Shining (1980) prompted further Steadicam innovation when director Stanley Kubrick requested that the camera shoot from barely above the floor. This necessitated the invention of "low mode", in which the top of the camera is mounted to the bottom of an inverted post, which substantially increased the creative angles of the system which previously could not go much lower than the operator's waist height.[4]
A Steadicam rig was also employed during the filming of Return of the Jedi (1983), in conjunction with two gyroscopes for extra stabilization, to film the background plates for the speeder bike chase. Brown walked through a redwood forest, with the camera running at a speed of less than one frame per second. The result, when projected at 24 frames per second, gave the impression of flying through the air at perilous speeds.[5][6] In the Michael Crichton film Runaway (1984), a Steadicam rig was used to simulate the point of view of a futuristic smart bullet in flight while targeting specific individuals by their heat signature.
The Steadicam system includes a harness, known as the Steadicam vest, which the operator wears. This vest is connected to an iso-elastic arm, which in turn is linked to a multi-axis, ultra-low friction gimbal. Attached to the gimbal is the Steadicam "sled," which supports the camera at one end and counterbalancing weights—typically a monitor and batteries—at the other. The monitor serves as a substitute for the camera's viewfinder, which becomes unusable due to the camera's range of motion relative to the operator. The design ensures that the Steadicam remains upright by maintaining the bottom slightly heavier than the top, pivoting around the gimbal. This configuration allows the operator to control the center of gravity of the rig, regardless of its weight, through precise movements of the gimbal. The operator's skill lies in maintaining the desired framing and composition by delicately adjusting the gimbal's position, whether in motion or stationary.[7]
The combined weight of the counterbalance and camera means that the armature bears a relatively high inertial mass which is not easily moved by small body movements from the operator. The freely pivoting armature adds additional stabilization to the photographed image, and makes the weight of the camera-sled assembly acceptable by allowing the body harness to support it.
When the armature is correctly balanced, operators can remove their hands from the Steadicam entirely and the camera stays in place. During operation, the Steadicam operator usually rests a hand on the camera gimbal and applies force at that point to move the camera. To avoid shaking the camera when lens adjustments are made, a wireless remote operated by the camera assistant is used to control focus and iris.
For low-angle shots, the Steadicam sled can be inverted vertically, putting the camera on the bottom, and the monitor and batteries on the top. This is referred to as low mode operation.
The newest generation is the Tango. A body-supported camera-stabilization-system, its horizontal mechanism makes it possible to move the camera freely while staying horizontal. A Steadicam operator can change from low mode to high mode without any alteration. Dimensions are not limited to ups and downs, but also in depth and over or through obstacles.
The smallest, lightest Steadicam that can be used with a support arm and vest is the Merlin. Photographers who shoot with HDSLR cameras that combine still and motion photography most often work with the Merlin. Since the Merlin has no facility to carry a separate monitor, cameras suitable for it must have built-in monitors.
Steadicam introduced a camera mount for smartphones, called the Smoothee, in 2012. Marketed to consumers instead of video professionals, its tubular frame supports iPhone and Android phones that are 4.53" to 6.26" long by 2.32" to 3.27" wide (115 to 159 mm long by 59 to 83 mm wide).[8] An adapter can be used to fit a GoPro camera to it.
