Technology Binoculars

Various types and characteristics of image stabilization technology

Presently, there are three makers, including Canon, selling binoculars with image stabilization technology.
  1. Vari-Angle Prism type
    Two sensors detect horizontal and vertical shaking respectively. The two Vari-Angle Prisms in both the left and right telescopes are controlled by a microprocessor to instantly adjust refraction angle of the incoming light. This system is used in Canons IS Binoculars.

    Advantages: compact, light; immediate response after the image stabilizer is activated (the system is activated as soon as the button is pressed); stable image even when panning.
    Disadvantage:  requires batteries.
  2. Gyro type
    A high-speed motor-driven gyroscope is attached to a prism. No matter how much the binoculars are shaken, the image will remain stable. This system is used in Fujinons Stabiscope S1240 and S1640.

    Advantage:  extremely resistant to heavy shaking or movement.
    Disadvantages:  one minute delay while the 12,000 rpm motor is starting up; tend to be heavy; this system is unable to distinguish between shake and panning, therefore image is not stable when panning; requires batteries.
  3. Mechanical type
    The prism system is tied-in with the Cardanic Suspension system, which prevents the prisms from moving no matter how much the binoculars are shaken. This system is used in the Zeiss 20x60S Professional.

    Advantages: no batteries required because of mechanical system; immediate response after the image stabilizer is activated (the system is activated as soon as the button is pressed).
    Disadvantages: tend to be heavy; this system is unable to distinguish between shake and panning, therefore the image is not stable when panning.
