ZOOMING

Rotate zooming ring (9) of the lens while viewing through the camera’s viewfinder and compose your image at the chosen focal length.

ZOOM LOCK SWITCH

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 (11) toward the camera, until the index lines align with each other. The lens 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 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 when locked.

-The lens can be used at 18mm setting for picture-taking even when locked by the switch. -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.

LENS HOOD

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

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 of the lens. Press the hood lightly. The lens hood will be secure when the mark “TAMRON O” is at the top. When attaching the lens hood, hold the focus and zoom control rings, so they are not rotated unintentionally.

-Pay particular attention to align the hood attaching indexes when using zoom lenses including wide-angle setting. 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

Reverse the lens hood. Point the lens toward the opening, and then align the hood attaching index on the lens with the “TAMRON O” alignment on the hood.

Turn the hood clockwise until the alignment mark is at the top to set it.
