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

ZOOMING (Ref. Fig. 2)
Rotate the zoom ring while viewing through the camera's viewfinder and compose
your image with right focal length obtained.
LENS APERTURE AND AE MODE (Ref. Fig. 7 & 8)
Setting lens f-numbers with Canon & Minolta cameras
Set the f-number with aperture setting device of the camera body in accordance with the
selected photographing mode.
* For further details, please read the instruction manual of your camera.
Setting the f-numbers with Nikon & Pentax cameras
Photographing in a programmed-AE or a shutter-speed-priority-AE mode, rotate the lens
aperture ring to the minimum aperture setting position, in the case of a Nikon camera, and
set on the "A" position in the case of a Pentax camera. The aperture ring will be locked in
position automatically. When shooting in an aperture-priority-AE or manual-exposure mode,
release the lens aperture ring by rotating the ring from the AE lock position and depressing
the Aperture ring lock button. If your camera is a Nikon F401 or F50, you can set the aper-
ture to any desired f-number, leaving the aperture ring at the minimum opening position.
* The lens aperture varies with zooming movement. Cameras read the different lens open-
ings and automatically adjust the exposure properly.
* For further details, please read the instruction manual of your camera.
LENS HOOD (Ref. Figs. 1, 9, 10 & 11)
A bayonet-type lens hood is provided as a standard accessory. We recommend shooting
with the hood attached whenever possible as the lens hood eliminates stray light, which is
harmful to the picture. However, please be aware of the precautions written below when
your camera is equipped with a built-in flash.
Attaching the Lens Hood (Ref. Fig. 9 & 10)
Align the index mark on the hood with the corresponding index mark (O or the top of the
index line of the distance scale) on the lens. Press the hood lightly onto the hood attaching
bayonet ring (Fig. 9, No. 1) and then rotate it clockwise to secure (Fig. 9, No. 2). The lens hood
will be securely held as the mark "TAMRON O" comes to the top (Fig. 10, No. 3). When attach-
ing the lens hood, hold the focusing and zoom control rings so that they are not rotated
unintentionally.
* Pay particular attention to align the hood attaching indices when using zoom lenses
including wise-angle (i.e. 35mm or wider) settings. Improper attachment of a hood for wide-
angle zoom lens may cause large shadowed areas in your pictures.

LENS HOOD (Ref. Figs. 1, 9, 10 & 11) (con’t)
Stowing Lens Hood
a. Detach and reverse lens hood then, align alignment mark of lens hood (TAMRON O) with
alignment mark of lens. (Fig. 11,a).
b. Press lens hood evenly onto bayonet ring and turn hood clockwise until stop. When
stopped, alignment mark of hood will be placed at top.
DEPTH OF FIELD
With a camera equipped with a depth-of-field-preview button or a aperture-stop-down
mechanism, the depth-of-field can be directly observed on the viewfinder screen of your
camera. For the operational details, read the instruction manual of your camera.
* In case you need a depth-of-field table of your lens, please ask for it at a Tamron distribu-
tor or a service station.
INFRARED PHOTOGRAPHY
Please be aware that there is no infrared index line on any models listed on this owner's
manual, and therefore, practically no black-and-white infrared film can be used with these
lenses.
PRECAUTIONS IN SHOOTING
When the built-in flash on the camera is used, adverse photographic phenomena such as
corner illumination fall-off or vignetting at the bottom part of the image may be observed,
especially in wide-angle ranges.This is due to the inherent limitation of coverage of the
built-in flash, and/or the relative position of the flash to the edge of the lens barrel, which
causes shadows on the image. It is strongly recommended to use a suitable separate flash
unit provided by the camera manufacturer for all flash photography.
* For further details, please read the "built-in flash article on the instruction manual of your
camera.

PRECAUTIONS IN SHOOTING (con’t)
When using the lens in the telephoto focal range, it may be necessary to use a tripod
to avoid camera shake. Using high-speed film (ISO 400 or faster) with a fast shutter speed is
also helpful to reduce the influence of camera shake.
Tele-converters are efficient tools to add focal length to the photographer's telephoto
lenses including zoom lenses but cannot be recommended for use with wide-angle lenses
or zoom lenses that cover wide-angle range focal lengths.
* When a tele-converter is attached, the focal length of the lens becomes longer but the
depth of field becomes shallower and it may be difficult to focus in AF mode. Therefore,
focusing in MF (Manual Focusing) mode is recommended when a tele-converter is used. 2X
tele-converters cannot be used with this lens. Do not use 2X tele-converters.
Certain camera models may indicate the maximum and minimum aperture values of
the lens as inappropriate numbers. This is inherent to the design of the camera and not an
indication of an error.
TO ENSURE LONG-TERM SATISFACTION
Avoid touching the glass element surface. Use a photographic lens cloth or blower to
remove dust from the lens element surface.When not using the lens, always place a lens cap
on it for protection.
Use a lens cleaning tissue or a 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 the
edge. Use a silicon cloth to clean your lens barrel only.
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. When storing the lens in a lens
case, store it with a commercially available drying agent such as silica gel, and change the
agent occasionally. If you find mildew on your lens, consult a repair shop or nearby photo-
graphic store.
Do not touch the lens-camera interface contacts since dust, dirt and/or stains may
cause contact failure between the lens and camera.
When using your equipment [camera(s) and lens(es)] in an environment where the
temperature changes from one extreme to the other, make sure to put your equipment
temporarily in a case or a plastic bag for a length of time in order for the equipment to go
through a gradual temperature shift. This will reduce potential equipment trouble.
