ZOOM LOCK SWITCH (Ref. Figs. 3 & 4)
Model A16 is equipped with zoom lock switch mechanism which prevent lens barrel from
extending towards long focal length, while hanging around the neck. Activate the switch at
the shortest setting to stop the lens barrels 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 (12) toward the camera for locking the zooming ring (9). The lens barrel is locked in
position when the portion beneath "Lock" is shown in red and the lens barrel does not
rotate or extend by its own weight.
2. Releasing: Push the zoom lock switch (12) up.The zooming ring (9) is now released and
can be rotated.
Zoom lock switch cannot be activated unless the lens is set to the shortest position. 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 used in a low
or high angle position.
The lens can be used at the shortest setting for picture taking even while in the focused position.
LENS APERTURE AND AE MODE
Please follow the instruction manual of your camera.
LENS HOOD (Ref. Figs. 1, 7, 8, 9)
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 written below when
your camera is equipped with a built-in flash.
Attaching the Lens Hood (Ref. Figs. 7 & 8)
Align the index 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 attach-
ing bayonet ring (Fig. 7, No. 1) and then rotate it clockwise to secure (Fig. 7, No. 2). The lens
hood will be securely held as the mark "TAMRON O" comes to the top (Fig. 8, No. 3). When
attaching 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 indexes when using zoom lenses including
wide-angle (ex. 35mm or wider) settings. Improper attachment of a hood for wide-angle zoom lens may
cause large shadowed areas in your pictures.
