to ON.
(Ref. Fig. )
■
Switching the modes (Ref. Fig. )
You can switch the modes by using the VC mode switch
⑳
.
MODE 1
Basic vibration compensation mode
MODE 2
Panning mode
MODE 3
Mode that prioritizes framing. Makes it easier to maintain subjects moving quickly
within the frame.
* MODE 1 and MODE 3 do not support panning.
●
Vibration compensation is effective under the following conditions
•
Dimly lit locations
•
Locations where flash photography is prohibited
•
Locations where tripod cannot be used
●
Vibrations may not be compensated sufficiently under the following conditions
•
When a photograph is taken from a vehicle that is shaking greatly
•
Shooting during excessive movement of the camera
•
When shooting while using a tripod
•
Set the VC switch
⑲
to OFF when taking pictures with bulb photography (long exposures).
Otherwise, vibration compensation may cause a malfunction.
•
When MODE 1 or MODE 2 is set, the viewfinder image may become blurred immediately after the
shutter button is pressed halfway. This is due to the principles of the vibration compensation
mechanism and not a malfunction.
•
When MODE 3 is set, the viewfinder image may become blurred even without touching the shutter
button in the case the camera is turned on with the VC switch
⑲
set to ON. This is due to the
principles of the vibration compensation mechanism and not a malfunction.
•
Set the VC switch
⑲
to OFF when you are shooting while the camera is secured by something
other than your hand (such as a tripod).
•
You may feel the lens rattle when the camera is turned off or when the lens is removed from the
camera. This is not a malfunction.
•
For details, please read the instruction manual of your camera.

SAFETY LOCK SCREW (Accessory for the tripod mount) (Ref. Figs. , )
We recommend attaching the lock screws in accordance with the camera platform type when you
use an ARCA-SWISS-standard compatible camera platform or clamp.
■
How to use safety lock screws (Ref. Fig. )
The safety lock screws
⑭
prevent the lens/camera from falling from the camera platform
when a tripod mount
⑩
is attached to an ARCA-SWISS-standard compatible camera platform
or clamp.
As shown on the figure, use the hexagonal wrench
⑮
to tighten the safety lock screws
⑭
to
the two screw holes
⑬
.
•
After attaching the safety lock screws
⑭
, the screw heads protrude from the tripod mount
⑩
bottom
surface to prevent the lens/camera from falling. For this reason, if you are using a camera platform or a
clamp other than ARCA- SWISS-standard compatible, you do not need to have them attached.
USAGE PRECAUTIONS
•
An internal focusing (IF) system is employed to reduce the minimum focus distance. The angle of
view may be wider than that of lenses with other focusing systems when shooting at a distance
less than infinity.
•
The lens hood or the lens barrel may block the light from the flash. It is recommended to
perform trial shooting in advance.
•
Differences in the display systems of cameras may cause to show values different from the
maximum and minimum aperture values from the specifications. This is not an indication of an
error.
•
Do not touch the lens-camera interface contacts with your fingers. Otherwise, it may cause a
malfunction.
•
If the temperature changes suddenly, condensation may form and cause malfunctions.
•
The front element is covered with stain-proof coating. After removing the dust on the lens
surface with a blower or another means, wipe it with a dry cloth.
•
Never use benzene, thinner, or other organic solvents to clean the lens.
•
Store the lens in a clean and well-ventilated place.
•
