THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. 
OPERATION IS SUBJECT TO THE FOLLOWING TWO CONDITIONS:
(1) THIS DEVICE MAY NOT CAUSE HARMFUL INTERFERENCE, 
AND (2) THIS DEVICE MUST ACCEPT ANY INTERFERENCE 
RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE 
UNDESIRED OPERATION.

You are cautioned that any changes or modifications not expressly approved 
in this manual could void your authority to operate this equipment.

NOTE:
This equipment has been tested and found to comply with the limits for a 
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits 
are designed to provide reasonable protection against harmful interference 
in a residential installation. This equipment generates, uses, and can radiate 
radio frequency energy and, if not installed and used in accordance with the 
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular 
installation. If this equipment does cause harmful interference to radio or 
television reception, which can be determined by turning the equipment off 
and on, the user is encouraged to try to correct the interference by one or 
more of the following measures:

– Reorient or relocate the receiving antenna.
– Increase the separation between the equipment and receiver.
– Connect the equipment into an outlet on a circuit different from that to which the 

receiver is connected.

– Consult the dealer or an experienced radio/TV technician for help.

This Class B digital apparatus complies with Canadian ICES-003.

•  Do not leave the lens in direct sunlight. If sunlight is focused onto a nearby 

object, it may cause a fire. If circumstances necessitate leaving the lens in direct 
sunlight, be sure to attach the lens cap.

•  Be careful not to subject the lens to mechanical shock while attaching it.
•  Always place the lens caps on the lens when storing.
•  Do not keep the lens in a very humid place for a long period of time to prevent 

mold.

•  Hold both the camera and lens, when you carry the camera with the lens 

attached.

•  Do not touch the lens contacts. If dirt, etc., gets on the lens contacts, it may 

interfere or prevent the sending and receiving of signals between the lens and the 
camera, resulting in operational malfunction.

Vignetting
When you use lens, the corners of the screen become darker than the center. 
To reduce this phenomena (called vignetting), close the aperture by 1 to 2 
stops.

Condensation
If your lens is brought directly from a cold place to a warm place, 
condensation may appear on the lens. To avoid this, place the lens in a plastic 
bag or something similar. When the air temperature inside the bag reaches 
the surrounding temperature, take the lens out.

•  Do not touch the surface of the lens directly.
•  If the lens gets dirty, brush off dust with a lens blower and wipe with a soft, 

clean cloth (Cleaning Cloth KK-CA (optional) is recommended).

•  Do not use any organic solvent, such as thinner or benzine, to clean the lens or 

the camera cone.

Operating Instructions

11(1)

 Attaching/detaching the lens

  Remove the front and rear lens caps and the camera body cap.

  Align the orange index on the lens barrel with the orange index on the 

camera (mounting index), then insert the lens into the camera mount and 
rotate it clockwise until it locks.

•  Do not press the lens release button on the camera when mounting the lens.
•  Do not mount the lens at an angle.

While pressing and holding the lens release button on the camera, rotate the 
lens counterclockwise until it stops, then detach the lens.

 Attaching a tripod

Attach the tripod to the lens, not to the camera.

Loosen the collar-locking knob on the tripod-mounting collar (1) and rotate the camera either 
direction. The camera can be quickly switched between vertical and horizontal positions while 
maintaining stability when using a tripod.

•  Gray indexes (collar indexes) are located at 90° intervals on the tripod-mounting collar. Align a 

gray index on the tripod-mounting collar with the gray index (collar index) on the lens to adjust the 
camera position precisely (2).

•  Tighten the collar-locking knob firmly after the camera position is set.

The tripod-mounting collar can be detached.

  Remove the lens from the camera.

•  See “

 Attaching/detaching the lens” for details.

  Loosen the collar-locking knob (1).

  Rotate the tripod-mounting collar to align the red index on the tripod-

mounting collar (collar mounting index next to SET/RELEASE) with the 
orange index on the lens (mounting index) (3).

  Move the tripod-mounting collar towards the lens mount and detach the tripod-mounting collar from the lens (4).

 Attaching the lens hood

It is recommended that you use a lens hood to reduce flare and ensure maximum image quality.

Loosen the locking screw on the lens hood and slip the lens hood over the front 
of the lens. Check that lens hood is attached properly, and then tighten the 
screw.

•  When using a built-in camera flash, make sure to remove the lens hood to avoid blockage of the 

flash light.

•  When storing, turn the lens hood back over the lens, and tighten the screw to secure the lens hood 

to the lens.

 Attaching the strap

Attach the strap so that the lens can be carried easily. Follow steps (1) and (2) to attach the 
strap.

•  To prevent the lens from dropping, be sure to attach the strap properly so that the strap will not 

come loose from the lens.

 Focusing

The focus mode can be switched between AF and MF on the lens.
For AF photography, both the camera and lens should be set to AF. For MF photography, either or both the camera or lens 
should be set to MF.

•  The focusing ring can be rotated slightly past the infinity to provide accurate focusing under various operating temperatures. Do not 

rotate the focusing ring all the way to the end when focusing manually, even at infinity. Look through the viewfinder and set the focus 
precisely.

To set the focus mode on the lens
Slide the focus-mode switch to the appropriate mode, AF or MF (1).

•  Refer to the camera manuals to set the focus mode of the camera.
•  In MF, turn the focusing ring to adjust the focus (2) while looking through the viewfinder. The focus signal in the viewfinder 

indicates the current condition of the focus.

•  Press the AF/MF control button to switch AF to MF when both the camera and lens are set to AF.
•  Press the AF/MF control button to switch MF to AF when the camera is set to MF and the lens is set to AF.
