ATTACHING AND REMOVING THE LENS
How to mount the lens
Removing the rear cap of the lens. Align the Lens attachment mark
insert the lens.
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 on the camera down, turn the lens counter-clockwise (in case of Nikon lens, clockwise), 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.
In case of a Nikon or Canon camera, switch the AF/MF switch
selector dial, set the focus mode to S or C, and then set the AF/MF switch
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 photograph.
In case of a Sony camera, switch the AF/MF switch
Press the shutter button halfway down 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 photograph.
When set on AF mode, interfering with focusing ring ⑥ may cause serious damage to the lens mechanism.
The distance scale ⑦ is marked for guidance purposes. The actual focal point may slightly differ from the distance marked on the
focal length index.
For further details, please read the instruction manual of your camera.
FOCUSING (Manual Focus) (
In case of a Nikon or Canon camera, switch the AF/MF switch
selector dial, set the focus mode to M, and then set the AF/MF switch
viewing through the camera's viewfinder (Fig.
In case of a Sony camera, switch the AF/MF switch
(MF). Focus manually rotating the focusing ring
will be sharp when the lens is focused correctly.
Even in the MF mode, when turning focusing ring ⑥ while pressing the shutter button halfway, the focus aid function lamp lights up when the
picture is in focus.
At infinity, make sure the image in the viewfinder appears sharp. The infinity position is made with certain allowances to insure proper focus
under a variety of conditions.
For further details, please read the instruction manual of your camera.
VC MECHANISM (Ref. Figs.
VC (Vibration Compensation) is a mechanism which reduces the image blur caused by hand-held shooting. When using the VC, pictures can
be taken at shutter speeds up to a maximum 4 stops slower than the speed when the VC is not used.
Based on the company's standard measurement. Also, the correction of image blur differs depending on the conditions during picture
＊
taking and the person using the camera.
How to use VC mechanism
1) Set the VC switch
⑫
*When VC is not used, set the switch off.
2) Press the shutter button halfway to verify the effect of the VC.
When the shutter button is pressed down halfway, it takes about 1 second for the VC to provide a stable image.
The VC can be effective for hand-held shots under the following conditions.
Dimly lit locations
Scenes where flash photography is forbidden
Situations where your footing is uncertain
Taking panning shots of a moving subject
The VC may not be able to give full effect in the following cases:
When a photograph is taken from a fast movimg vehicle
Shooting during the excessive movement of the camera
Turn the VC switch OFF when taking pictures with the bulb setting or during long exposures. If the VC switch is ON, the VC mechanism
may introduce errors.
With the VC mechanism, there are occasions that the image in the viewfinder blurs right after the shutter button is pressed down
halfway, but this is not a malfunction.
When the VC is ON, the number of images recordable is reduced due to the power used from the camera.
When the VC is ON, immediately after the shutter button is pushed halfway down and approximately 2 seconds after a finger releases
the shutter button, the camera will "click". This sound is the VC's locking mechanism activating, not a malfunction.
Turn the VC swtich OFF when using tripod.
After releasing the shutter button, the VC will continue to operate for about 2 seconds until the locking mechanism activates.
When the lens is removed from the camera while VC is activating, the lens may make clicking sound when the lens is subjected to a jolt. This is
not a malfunction. Re-attach the lens to the camera and turn the power ON. The sound should stop.
The VC activates while the "release" button is pushed halfway down. (It is activated 2 seconds after the shutter button is released)
VC can be used in AF or MF mode.
ZOOMING (Ref. Figs.
Rotate zooming ring
of the lens while viewing through the camera's viewfinder and compose your image at the chosen focal length.
⑨
ZOOM LOCK SWITCH (Ref. Figs.
Zoom lock switch mechanism prevents lens barrels from extending toward long focal length by their own weight while hanging from
shoulders. Activate the switch at 18mm setting to stop the lens barrels from rotating and extending.
How to activate the zoom lock switch mechanism
1) Locking: Set the lens to the 18mm position. Move the switch
barrel is now locked in position and does not rotate or extend by its own weight.
2) Releasing: Push the switch away from your camera. The lens barrel is now free to rotate and extend for zooming.
The zoom lock switch ⑪ cannot be activated unless the lens is set to the 18mm position. Do not force the lock switch or try to
rotate the lens barrel while locked.
The zoom lock mechanism is made to prevent the lens barrel from extending while carried around on shoulder. The lens may
change its focal length during a long exposure if the lens is used in a low or high angle position.
The lens can be used at 18mm setting for picture-taking even when locked by the switch.
LENS HOOD (Ref. Figs.
A bayonet-type lens hood is provided as standard equipment. 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 stated in the next section when your
camera is equipped with a built-in flash.
Attaching the Lens Hood (Ref. Figs.
Align Hood attaching alignment mark ② on the hood with the corresponding index mark ⑤ 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.
secure (Fig.
hold the focus and zoom control rings so that they are not rotated unintentionally.
Pay particular attention to align the hood attaching indexes when using zoom lenses including wide-angle (e.i. 35mm or wider)
settings.
Improper attachment of a hood on a wide-angle zoom lens may cause large shadowed areas in your pictures.
Stowing lens hood on the lens (Ref. Fig.
1) Reverse the lens hood. Point the lens toward the opening, then align the hood attaching index on the lens with the (TAMRON
alignment on the hood
2) Turn the hood clockwise until the alignment mark (•) is at the top to set it. (Fig.
PRECAUTIONS IN SHOOTING
The optical design for Di II takes into consideration the various features of digital single reflex cameras. However, due to the configuration of
the digital single reflex cameras, even when the autofocus accuracy is within specifications, the focal point may be a little forward or behind
the optimum point when shooting with autofocus under some conditions.
The image circles of Di II lenses are designed to match the digital SLR cameras using the image sensors equivalent to APS-C (approx.
15.5 23.2mm). Do not use Di II lenses with cameras using image sensors larger than APS-C. Using Di II lenses with such cameras may
cause vignetting on the image.
The Tamron lenses described here employ an internal focusing (IF) system. Because of the characteristics of this optical design, the angles
of view at distances other than infinity are wider than that of the lenses applying an ordinary focusing system.
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 the 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.
When set on AF mode, interfering with focusing ring may cause serious damage to the lens mechanism.
Certain camera models may indicate the maximum and minimum aperture values of the lens in approximate numbers. This is inherent to
the design of the camera and not an indication of an error.
Please be aware that there is no infrared index line on any models listed in this owner's manual, and therefore, practically, no black-and-
white infrared film can be used with these lenses.
When using a special filter such as a PL filter, use low profile filters. The thick rim of a normal filter may cause vignetting.
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 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 an lens case, store it with commercially available drying agent such as silicagel, and change the agent
occasionally. If you find mildew on your lens, consult an authorized repair shop or nearby photographic store.
Do not touch the lens-camera interface contacts since dust, dirt and/or stains may cause a 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.
