 Attaching/detaching the lens
To attach the lens
1
Remove the front and rear lens caps and the camera body cap.
To switch AF (auto focus)/MF (manual focus)
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.
(1)
Attach the tripod to the lens, not to the camera.
To change vertical/horizontal position
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.

 SET: AF is set to the appointed focus range, both far and near positions.
To set the signal off, slide the audio-signal switch to OFF.
 Changing the plug-in filters
A normal filter is equipped with your lens.
 The
filter is a part of optical system component. Be sure to attach either the
normal filter or the polarizing (circular) filter when taking pictures.
Direct manual focus (DMF)
Even when AF is set, the setting is switched to MF automatically if you rotate
the focusing ring while pressing the shutter button halfway. This provides
quick fine adjustment of focusing (DMF). Select the mode for correct DMF
from the following. Set the DMF-mode switch to whichever you prefer.

Standard DMF (STD)
Rotate the focusing ring to set correct DMF when the focus is locked in AF-A
(automatic auto focus) or AF-S (single-shot auto focus). Using this mode is
recommended for normal subjects.

Depth-of-field scale (See Exhibit  Operating
Instructions-)
Focus the lens to the desired far or near distance.
depth-of-field scale and depth-of-field table are for 35mm-format cameras.
The depth-of-field is shallower when you use an Interchangeable Lens Digital
Camera equipped with an APS-C sized image sensor.
 Using focus-hold buttons
This lens has 4 focus-hold buttons.
Press the focus-hold button in AF to cancel AF. The focus is fixed and you
can release the shutter on the fixed focus. Release the focus-hold button while
pressing the shutter button halfway to start AF again.
Align the filter-holder lock orange index with the filter holder,
face the side with the filter to the camera body, and then insert
the filter holder into the lens barrel.
 When
attaching the polarizing (circular) filter to the lens, make sure to
point the arrow tip of the filter holder to the lens front.

 Using prefocus
Push down the filter-holder lock and turn it 90° clockwise to lock.
 The
filter-holder lock orange index is perpendicular to the holder.
A specific subject distance can be stored and recalled at any time. With the
distance set, this is useful for catching fast-moving subjects, such as a moving
train, events at a sports festival, or horse and car races, etc.
When focus is set on a subject, anything at that same distance will appear
sharp, and anything within a certain range before and beyond the subject will
also appear in focus; this is called depth of field. Depth of field depends on
the subject distance and aperture you choose and is indicated by the lines on
the depth-of-field scale corresponding to the aperture.

In any AF mode (AF-A/S/C), rotate the focusing ring while pressing the
shutter button halfway to set correct DMF. This is useful to catch a fastmoving subject.
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, etc., and set the focus precisely.

 Using the audio signal
 Switching focus range (AF range)
The audio signal beeps when the focusing range is customized with the
focus-range setting switch or the prefocus distance is set or recalled with the
focus preset button.
The focus-range limiter enables you to reduce the auto focusing time. This is
useful when the subject distance is definite. You can also set the desired focus
range and select it.
Slide the focus-range limiter to select the focus range.
Slide the audio-signal switch to BEEP ON to activate the signal.
 The
polarizing (circular) filter can reduce or eliminate unwanted reflections
(polarized light) from nonmetallic surfaces of water, glass, windows, shiny
plastics, ceramics, paper, etc. It can also filter out polarized light from
the atmosphere in general to produce richer colors. You can adjust the
polarizing degree to get good contrast when taking photos of blue sky.
 Generally, reflected light (polarization) should be minimized in
photography, however you can adjust the polarizing degree for the desired
effect.
 The amount of light reaching the image sensor decreases. If your camera is
set to manual exposure mode and you are using a commercially available
exposure meter, or if your camera is set to manual exposure mode and you
are using the Manual Flash Control function available on some external
flash units, adjust the exposure compensation by opening the aperture 1 or
2 stops to the + side.
