MOUNTING / REMOVING LENS (Fig. 2)
Mounting
After removing the rear lens cap, align the lens mount index mark with that of the camera
body (on Canon/Minolta/Pentax models) and rotate the lens clockwise until it click-locks.
For the Nikon model, align the lens mount index mark with the dot on the camera and
rotate counter-clockwise until it click-locks.
Removal
Push in and hold the lens release button on the camera body while rotating the lens count-
er-clockwise (clockwise in case of Nikon model) and lift the lens off the camera body.
* Refer to the instruction manual of your camera for additional information.
FOCUSING (Fig. 2 and 3)
Switching between AF & MF modes
Nikon and Canon models: Simply move the focusing ring forward (to AF) and backward (to
MF) to change the focusing mode between autofocus (AF) and manual focus (MF).
Minolta and Pentax models: Move the focusing ring forward (to AF) and backward (to MF)
and at the same time, set the AF/MF selector switch of the camera body to the coinciding
focusing mode (AF or MF).
Mount AF/MF Switching Operation
Nikon AF-D Move focusing ring only.
Minolta Move and switch both focusing ring and
selector of camera body.
Canon Move focusing ring only.
Pentax Move and switch both focusing ring and
selector of camera body.
* Carefully read "Autofocus" and "Manual focus" sections below and operate the camera and
lens accordingly. In addition, please refer to the instructions related to focusing operations
of your camera.
AUTOFOCUS (AF)
The camera focuses automatically in the AF mode, provided both focusing ring of the lens
and the AF/MF selector switch of the camera body are set to the autofocus mode (AF).The
focusing ring does not rotate when set in the AF mode since the coupling mechanism of
the focusing ring is disconnected from the autofocus mechanism.Therefore, the focus ring
itself will rotate freely when manually turned, but will have no effect on focus adjustment.

CAUTION WHEN OPERATING MINOLTA AND PENTAX MODELS
When the focusing ring is set in the manual focus position while the camera is set in
the AF mode, the focusing ring rotates as if it were in autofocus mode.Turning of the focus
ring in this instance may cause damage to the lens and/or the camera.
Do not force the focusing ring when it is set in the manual focus mode. Manual rota-
tion of the focus ring when the camera is still set in the autofocus mode (AF) will cause
mechanical damage to the lens and/or to the camera body.
MANUAL FOCUS (MF)
Nikon and Canon models: Simply move the focusing ring backward to the MF position.
Minolta and Pentax models: Switch the AF/MF selector switch on the camera body to MF
mode then, slide the focusing ring backward to the MF position.
MANUAL FOCUSING OPERATIONS
Rotate the focusing ring manually while looking through the viewfinder until the image in
the finder comes into sharp focus.
When the focusing ring is set to the AF position, the focusing ring rotates freely and
you cannot adjust focus.
If you use the lens in the manual focus mode on an autofocus camera, rotate the
focusing ring while holding the shutter release button depressed halfway. The focus confir-
mation indicator will light when subject comes into focus.
The focusing ring of this lens of this lens rotated beyond the infinity position in order
to properly focus to infinity under a variety of environmental conditions. When manually
focusing, make sure the subject at infinity is sharp in the viewfinder.
APERTURE (Fig. 4 and 5)
Canon and Minolta models
Lens apertures are set and controlled by the camera by the camera according to the mode
set on the camera body.
Nikon and Pentax models
When photographing in the programmed AE or the shutter-speed-priority AE mode, rotate
the aperture ring to the minimum opening (f/22) position on the Nikon model and to AE
position on the Pentax model by depressing the AE lock button.The aperture ring will auto-
matically lock in position. To switch to the aperture-priority AE or manual-exposure-control
mode, rotate the aperture ring to any desired f-number by depressing AE (minimum aper-
ture) lock button. In case of the Nikon F401 and/or F50 series cameras, the aperture can be
set on the camera body when the lens aperture ring is set in the minimum aperture posi-
tion.

INFRARED INDEX (Fig. 4)
Special focus adjustment is required when using infrared black and white film with an
infrared filter attached to the lens. Set the lens and the camera in manual focus mode and
focus normally.Then adjust the focusing scale to the infrared index and attach the infrared
filter to begin photographing. A critical focus may be obtained through test shooting(s).
LENS HOOD
A lens hood is built in as a part of this lens. In order to eliminate unnecessary and harmful
stray light rays from outside the ultra-wide angle of view of the lens, the lens hood is built in
as an inseparable part of the lens barrel. This built-in lens hood design also protects the
front convex lens element, which has an extremely large curvature.
CHECKING DEPTH OF FIELD (Refer to depth-of-field table)
The depth-of-field table shows aperture values horizontally at top and ranges of focus verti-
cally at left. If, for example, the aperture is set at f/4 and the distance to the subject is 1 m
(3.3ft), the depth-of-focus value is 0.67 - 2.24m (2.2 - 7.39 ft.)as read in the table where f/4 in
the horizontal column and 1m (3.3ft) in the vertical column intersect.
* Refer to the instruction manual of your camera for additional information.
* If your camera has a depth-of-field preview mechanism, the depth-of-field effect can
be confirmed in the viewfinder. For further details on the preview mechanism, refer to the
instruction manual of your camera.
FILTER (Fig. 6)
Due to the nature of this lens's ultra-wide angle of view, a filter cannot be attached to the
front of the lens barrel. A sheet type of filter, such as a gelatin filter, may be cut using the
template provided and inserted in the filter slot in the rear of the lens.
* Cut and trim a sheet-type filter to the size of the template. If the template is not followed
exactly, the filter may bend or, in some cases, snap out of position by the focusing move-
ment of the lens and therefore may not work effectively.
* Set the lens to the infinity position in order to insert or extract a filter from the filter slot of
the lens.

PRECAUTIONS
Generally, an ultra-wide lens is susceptible to optical flare and ghost images due to its
ultra-wide angle of view. Check the images carefully through the camera's viewfinder to
make sure there is no adverse flare, glare, or ghost image in the frame.
An ordinary flash device cannot cover the entire angle of view of this lens.Therefore,
unless you are intentionally using a single on-camera flash unit, it is best to photograph in
natural lighting or in extremely broad and flat lighting with multiple lighting units.The
built-in flash unit of a camera may cast a semi-circular shadow of the extending lens barrel
in a photograph.
Refer to the instruction manual of your camera relating to the built-in flash unit.
Set the focusing ring in the AF position when shooting in the AF mode.The ring set at
the MF position in the AF mode may cause damage to the lens and/or camera.
Certain camera models may indicate the maximum and minimum aperture values of
this lens in approximate numbers.This is inherent to the design of the camera and not an
indication of error.
If you use the data-memory card of the Minolta card system, the focal length of this
lens is registered as 15mm. Such a focal length registration is due to the memory system of
the camera and is not an indication of error.
When using the Pentax MZ-10 in the auto-picture-program mode, you may not be
able to set the camera to the "portrait" mode.The camera judges the appropriateness of the
set picture mode gathering data such as the focal length of the lens, the image magnifica-
tion and so on. When determined not appropriate, set picture mode is cancelled
TO ENSURE LONG-TERM SATISFACTION
1.Avoid touching the glass element surface. Use a photographic lens cloth or blower
brush to remove dust from the lens element surface. When not using the lens, always place
the supplied lens cap on it for protection.
2.Use a lens cleaning tissue or lint cloth with a drop of cleaning solution to remove
fingerprints or dirt on the glass lens surface with a rotary motion from the center to edge.
Use a silicon cloth to clean your lens barrel only.
3. Mildew is an enemy of your lens. Clean the lens after shooting near water or in any
humid place. Store your lens in a clean, cool and dry place. If you find mildew on your lens,
consult a repair shop or nearby photographic store immediately.
4.Do not touch the lens-camera interface contacts since dust, dirt and/or stains may
cause contact failure between the lens and camera.
5.When using your equipment [camera(s) and lens(es)] in an environment where the
temperature changes from one extreme to another, make sure to put your equipment tem-
porarily in a case or plastic bag for a period of time to allow the equipment to gradually
adjust to the temperature shift. This will reduce potential equipment trouble.
