ZOOMING
Rotate the zooming ring of the lens while viewing through the camera's viewfinder and compose your image at the chosen focal length.
ZOOM LOCK SWITCH
Model A014 is equipped with a zoom lock switch mechanism which prevents the lens barrel from extending towards longer focal lengths while being carried around the neck, or off the shoulder. Activate the switch at the shortest setting to stop the lens barrel from rotating and extending.
*How to activate the zoom lock switch mechanism
1.Locking: Set the zoom ring on the lens to the shortest position. Move the zoom lock switch toward the camera to lock the zooming ring.
2.Releasing: Push the zoom lock switch back up. The zooming ring is now released and can be rotated.
**Zoom lock switch cannot be activated unless the lens is set to the shortest posi- tion. Do not force the lock switch or try to rotate the zooming ring while locked; doing so may damage the lens.
**The zoom lock mechanism is made to prevent the lens barrel from extending while carried around the neck. When not locked, the zoom lens may change its focal length during a long exposure in a low or high angle.

Align the index mark on the hood with the corresponding index mark on the lens. Press the hood lightly onto the hood attaching bayonet ring and then rotate it clock- wise to secure. The lens hood will be securely held as the mark "TAMRON O" comes to the top. When attaching the lens hood, hold the focusing and zoom control rings so that they are not rotated unintentionally.
