Image Stabilizer Operation - Canon HJ40x10B Operation Manual

5-4. IMAGE STABILIZER OPERATION

The image stabilizer in this lens is provided with a mechanical lock mechanism for protecting the anti-
vibration optical system from shocks during transport. To make the image stabilizer active, the lock must be
released first, and then power must be supplied to the anti-vibration optical system driving circuits.
The image stabilizer can be used in one of two statuses when the lock is released. Switch to the required
status when in use.
Operating status where the anti-vibration optical system performs image
stabilization. ---------------------------------------------------------------------------------------------------------- IS ON
Standby status where the anti-vibration optical system is electrically held to the optical
axis center ---------------------------------------------------------------------------------------------------------- IS OFF
(A) RELEASING THE MECHANICAL LOCK
A mechanical lock is applied to the image stabilizer immediately after
the power is turned on from the camera. IS POWER ON lever at the
camera side next to the mount is used to release the lock and supply
power to the anti-vibration optical system driving circuits.
Turn IS POWER ON lever counterclockwise from the horizontal position
until it is nearly vertical. If you release the lever in this position, the lever
will lock and the image stabilizer is ready to be used. (The IS status
indicator LED on the lens drive unit lits and power supply to the anti-
vibration optical system driving circuits can be checked.)
*(NOTES): 1) If the IS POWER ON lever returns to the horizontal position without locking, the mechanical
lock has not been released. Then, turn the lever again to lock it in the vertical position.
2)To maximize its performance, the image stabilizer needs a warming-up for the first time
that the mechanical lock is released after turning on the power from camera. Although the
image stabilizer can still be used during this warming-up time, anti-vibration performance
may not be fully maximized.
(B) APPLYING THE MECHANICAL LOCK
In the image stabilizer in this lens, a mechanical lock is automatically ap-
plied to the anti-vibration optical system when the power supply to the
lens is cut off. Therefore, the mechanical lock does not need to be applied
manually when shooting is finished.
Also, because the anti-vibration optical system applies a mechanical lock
precisely at the optical axis center position, if the anti-vibration function is
not needed, shooting can be performed with the anti-vibration optical
system under a mechanical lock. This is the reason that IS POWER OFF
switch for cutting off power only to the anti-vibration optical system driving
circuits is located by IS POWER ON lever. If necessary, press this button to activate the mechanical lock.
Power can be saved by applying the mechanical lock since the anti-vibration optical system consumes a
slight amount of power even when it is inactive (standby status) due to its anti-vibration optical system driving
circuits.
IS POWER ON lever automatically moves to the horizontal position when the power to the lens is cut off or
when IS POWER OFF switch is pressed to apply the mechanical lock.
CAUTION: Be sure to use IS POWER OFF switch when applying the mechanical lock to the anti-vibra-
tion system during shooting. Never apply the mechanical lock by forcing back IS POWER
ON lever to the horizontal position. Otherwise the lens mechanism would be damaged.
