ATTACHING LENS TO CAMERA

How to mount the lens

Removing the rear cap of the lens, align the lens attachment mark on the lens barrel with its
counterpart on the lens mount of the camera and insert the lens mount into the camera's
mount opening. Rotate the lens clockwise until it click-locks. For Nikon models, align the
lens attachment mark with the dot on the camera and rotate the lens counter-clockwise
until it click-locks.

How  to detach the lens

Pressing the lens release button of the camera down, turn the lens counter-clockwise (clock-
wise in case on Nikon), and lift the lens off the camera's lens mount.
* For further details, please read the instruction manual of your camera.

FOCUSING (Autofocus) (Ref. Figs. 1 & 2)

Set the camera on the autofocus mode (AF). Press the shutter button lightly while viewing
through the camera's viewfinder, the lens focuses automatically. An in-focus mark will light
when lens focuses on the main subject sharply. Press the shutter button further to photo-
graph.
* Also, please read the camera's instruction booklet carefully.

When set on AF mode, be very careful not to hinder the autofocusing movements of

the lens. Such interference may cause a serious damage on the lens mechanism.

Select between the autofocus and manual focus modes by the AF/MF mode selector

switch on the lens barrel.
* For further details, please read the instruction manual of your camera.

FOCUSING (Manual Focus) (Ref. Fig. 2)

Switch the focusing mode switch of the camera to manual focusing mode (MF) in

case of Nikon, Minolta, or Pentax camera. In case of Canon, switch to MF on the AF-MF alter-
ing switch on the lens barrel. Focus manually, rotating the focusing ring while viewing
through the camera's viewfinder. The main subject image in the viewfinder will be critically
sharp on the viewfinder screen as lens focuses rightly.

Press the shutter button lightly while operating the lens for focusing. The focus aid

mark in the viewfinder will light up when the subject is in critical focus.

Make sure the subject at infinity appears sharp in the finder when in focus. Because,

the infinity position on the lens is made with certain allowance to assure right focus under a
wide variety of photographing conditions.
