Vibration Compensation Technology

Problem: Blurred Images

Certainly everybody knows this problem: The mood of the lighting at dusk is great, the subject in the viewfinder fits perfectly and now you frantically try to keep the camera stable to prevent the blurring of the image.

If you are lucky, the result is fairly sharp. Nevertheless, the danger is big, especially at longer shutter speeds and long focal lengths that you receive an unsharp and blurred picture.

The Solution: Tamron VC

Tamron developed the vibration Compensation ( VC) technology so that, in future you can concentrate completely on your subject and let your creativity run free.  This stabilizer formally freezes the picture in the viewfinder and allows you to exactly position and control the image in the viewfinder. With the VC stabilizer you win up to four stops more leeway to achieve optimum handheld results at longer focal lengths or with little light. You can also use the stabilizer to pan directly without changing the mode.

Functionality

A blurred image results on the image plane and as a result of camera vibrations. Gyro sensors sense the respective vibrations and pass the data to the microprocessor, which in turn calculates the angle of rotation and passes on control commands to the driving unit which shifts the element VC opposite to the direction of the vibration. ( VC Scheme)  

The Tamron Vibration Compensation mechanism employs a three-coil system in which three driving coils move internal optical components within the VC lens electromagnetically, based on signals originating from three steel ball bearings. Since the VC compensating lens elements are held in place solely by contact with these bearings, smooth, virtually frictionless movement is assured, providing stabilized viewfinder images and excellent tracking performance characteristic of VC lenses. (The system works at a speed of 4000Hz, meaning that a correction is performed 4000 times a second). Moreover, since the VC lens elements move parallel to the image plane via electronic control alone, the mechanical structure is simplified, and the lens is more compact. 

Creative Possibilities

Apart from the technical explanation, of main interest to photographers are the creative possibilities. In this gallery we present a selection of pictures which originated with VC.
