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 clockwise 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.

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

SWITCHING FOCUS MODE (Ref. Fig.  )

Select the desired focus mode on the camera.

For manual focusing, turn the focus ring 

 to acquire the desired focus.

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

 Under AF mode, there may be difficulty for autofocus to work depending on the subject.

ZOOMING (Ref. Fig.  )

Turn the zooming ring 

 to adjust the focal length (Zoom position) to a desired position.

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. Fig.  )

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.

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.

 Never use benzene, thinner, or other organic solvents to clean the lens.

 Store the lens in a clean and well-ventilated place.
