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 Canon' s IS
Binoculars.
Advantages:
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 Fujinon' s Stabiscope S1240
and S1640.
Advantage:
Disadvantages: • One minute delay while the 12,000 rpm motor

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:
Disadvantages: • Tend to be heavy.
• 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.
• Extremely resistant to heavy shaking or
movement.
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.
• 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).
• This system is unable to distinguish between
shake and panning; therefore the image is not
stable when panning.
