With the VC mechanism, there are occasions that the image in the viewfinder 
blurs right after the shutter button is pressed down halfway, but this is not a 
malfunction. 

 

When the VC switch is turned ON, the number of images recordable is reduced 
due to the power used from the camera. 

 

When the VC switch is turned ON, immediately after the shutter button is pushed 
halfway down and approximately 2 seconds after the shutter button has been 
released, the camera will “click”. This sound is the VC’s locking mechanism 
activating, it is not a malfunction. 

 

Turn the VC switch OFF when using a tripod. 

 

After releasing the shutter button, the VC will continue to operate for about 2 
seconds until the locking mechanism activates. 

 

 

When the lens is removed from the camera while VC is activating, the lens may 
make clicking sound when the lens is subjected to jolt. This is not a malfunction. 
Re-attach the lens to the camera and turn the power ON. The sound should stop.

 

 

The VC activates while the “release” button is pushed halfway down. (It is 
activated 2 seconds after the shutter button is released.) 

 

VC can be used in AF or MF mode.

 

 

For further details, please read the instruction manual of your camera.

 

 

ZOOMING (Ref. Fig. 1 & 2) 

 

Rotate the zooming ring (6) of the lens while viewing through the camera’s LCD 
and compose your image at the chosen focal length. 

 
ZOOM LOCK SWITCH (Ref. Fig 1, 3 & 4) 

Zoom lock switch mechanism prevents lens barrels from extending toward long focal 
length by their own weight while hanging from shoulders. Activate the switch at 18mm 
setting to stop the lens barrels from rotating and extending.  
 

How to activate the zoom lock switch mechanism 

1.

 

Locking: Set the lens to the 18mm position. Lift the zoom lock switch (9) toward 
the lens. The lens barrel is now locked in position and does not rotate or extend by 
its own weight. 

2.

 

Releasing: Pull the zoom lock switch (9) toward the camera. The lens barrel is 
now free to rotate and extend for zooming. 
 

 

The zoom lock switch (9) cannot be lifted unless the zoom index mark (8) is set to 
18mm. Do not force the lock switch or try to rotate the zooming ring (6) while 
locked. 

 

The zoom lock mechanism is made to prevent the lens barrel from extending while 
carried around on the shoulder. The lens may change its focal length during a 
long exposure if the lens is used in a low or high angle position. 

 

 

The lens can be used at 18mm setting for picture taking even when locked by the 
switch.
