ATTACHING AND REMOVING THE LENS
Remove the rear cap of the lens. Align the lens attachment mark and mounting mark on the
camera, and then insert the lens.
Turn the lens counterclockwise for Nikon models or clockwise for Canon models until it locks.
To remove the lens, turn the lens in the opposite direction while pressing the lens release button
on the camera.
 Turn off the power of the camera before attaching or removing the lens.
 In the case of Canon cameras, align with the EF lens mark (red circle).
 For details, please read the instruction manual of your camera.
SWITCHING FOCUS MODE (Ref. Figs. - )
To shoot using autofocus (AF), set the AF/MF switch to “AF”. (Ref. Fig. )
To shoot using manual focus (MF), set the AF/MF switch to “MF”, and then use your hand to
turn the focus ring and focus the image. (Ref. Figs. , )
You can limit the AF focus range by setting the AF/MF switch to “LIMIT”.
The focus range you may limit will differ depending on the current focus distance.
If the focus position is longer than 7 m: ∞-7 m
If the focus position is shorter than 7 m: 7 m-1.5 m
* You can change the AF range limit, which is set to 7 m by default, using the TAP-in Console
(sold separately).
 The distance scale is provided as a guideline. It may differ from the actual focus distance.
 In AF mode, it may be difficult for autofocus to work depending on the subject.
 Through the full-time manual mechanism, when focusing with AF, it is possible to switch to MF by turning
the focus ring while the AF/MF switch is set to AF. AF can be resumed by releasing your finger from
the shutter button and then repressing the shutter button halfway.
 To ensure focus under various conditions, the focus ring rotates past the infinity (∞) position.
Accordingly, always check the focus in the viewfinder when shooting with manual focus, even when the
focus is aligned with infinity.
 For details, please read the instruction manual of your camera.
VC MECHANISM (Ref. Figs. , , )
The VC (Vibration Compensation) mechanism reduces image blur caused by hand-held shooting.
 How to use VC (Ref. Figs. , )
You can change the VC mode by using the VC switch .
MODE 1 Basic mode that balances finder-image stability and the actual compensation effects.
MODE 2 Panning mode
* In MODE 1, you can change the settings using the TAP-in Console (sold separately).
 VC is effective under the following conditions
 Dimly lit locations
 Locations where flash photography is prohibited
 Locations where you have unstable standing position.
 VC may not perform 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 to OFF when taking pictures with bulb photography (long exposures).
Otherwise, VC may cause a malfunction.
 The viewfinder image may become blurred immediately after the shutter button is pressed
halfway. This is due to the principles of VC and not a malfunction.
 When the VC switch is set to ON, the total number of recordable images will reduce due to
power being consumed from the camera.
 Set the VC switch to OFF when you are shooting while the camera is secured by something
other than your hand (such as a tripod).
 Do not remove the lens from the camera while VC is on. If the lens is removed while VC is on, the
lens may make a clicking sound if the lens is shaken. This is not a malfunction. If the lens is
installed on the camera, and the camera’s power is switched on, the sound stops.
 For Nikon cameras equipped with a built-in flash, VC will be turned off while the built-in flash is
charging.
ZOOMING (Ref. Figs. , )
While looking through the camera’s viewfinder, rotate the zooming ring of the lens to set the
focal length suitable for the image, and then shoot.
ZOOM LOCK MECHANISM (Ref. Figs. , , )
You can lock the zooming ring at a focal length of 100mm to keep it from rotating.
 Setting the zoom lock (Ref. Fig. )
Align 100mm on the focal length scale with the focal length mark .
Push the zoom lock switch to the zooming ring side.
 Releasing the zoom lock (Ref. Fig. )
Push the zoom lock switch toward the camera.
 To zoom, release the lock, and then rotate the zooming ring.
LENS HOOD (Ref. Figs. , - )
A bayonet-type lens hood is provided as standard equipment.
We recommend shooting with the hood properly attached because the lens hood eliminates stray
light that may affect the picture.
 Using the lens hood (Ref. Figs. , )
Align the hood attaching alignment mark of the hood with the hood release mark of the
lens.
Rotate the hood
in the direction of the arrow until the hood locking mark meets the hood
release mark .
 Stowing the lens hood (Ref. Fig. )
You can stow the lens hood by attaching it in reverse.
Align the hood locking mark of the hood with the hood release mark of the lens.
Rotate the hood in the direction of the arrow until the hood attaching alignment mark
meets the hood release mark .
 Be aware that the perimeter of the photographed image may be darkened if the hood is not
attached properly.
TRIPOD MOUNT (Sold separately) (Ref. Figs. , , , )
You can secure the lens to the tripod using the tripod mount for A035 model (model A035TM
sold separately).
 Attaching and removing the tripod mount (Ref. Figs. , )
You can attach and remove the tripod mount by loosening tripod mount locking screw and
then lift the portion with the screw, to open the ring.
When attaching the tripod mount, make sure that the protruding part on the inner side of the
tripod mount is inserted into the groove on the lens barrel, and then tightly secure the tripod
mount locking screw
.
If this protruding part is not inserted into the groove when the tripod mount is attached, the
lens barrel may be damaged and the lens may fall off.
 Changing the directional position of the camera (Ref. Fig. )
When you change the directional position of the camera, you can rotate the lens by loosening
the tripod mount locking screw
.
Align the tripod mount mark on the lens with the mark on the tripod mount .
After determining the shooting position, tightly secure the tripod mount locking screw to fix
the position.
 The tripod mount can be attached to an ARCA-SWISS camera platform.
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 prevent the lens/camera from falling from the camera platform
when a tripod mount is attached to an ARCA-SWISS-standard compatible camera platform or
clamp.
As shown on the figure, use the hexagonal wrench
to tighten the safety lock screws to
the two screw holes .
 After attaching the safety lock screws , the screw heads protrude from the tripod mount 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.
PRECAUTIONS WHEN SHOOTING
 An internal focusing (IF) system is employed to reduce the minimum focus distance. Because of
this, the angle of view is wider than that of lenses using other focusing systems when shooting
at a distance less than infinity.
 Always remove the hood when you use the built-in flash on the camera for flash photography.
Otherwise, the hood or lens may darken the perimeter of the image. With close-up photography,
the lens itself blocks the flash, and dark semicircle may appear at the bottom of the screen, even
when the lens hood is not used. For flash photography, we recommend that you use an external
flash unit recommended by the camera manufacturer.
 Differences in the display systems of cameras may result in the display of values different from
the maximum and minimum aperture values in the specifications. This is not an indication of an
error.
 Use with mirrorless interchangeable-lens cameras is not guaranteed.
