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.

(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.
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.
