• VC can be used in AF or MF mode.
• For further details, please read the instruction manual of your camera.
ZOOMING (Ref. Fig. 1 & 2)
• Rotate the 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 (Ref. Fig 1, 3 & 4)
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 24mm
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 24mm 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 (11) away from the 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 24mm
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 the shoulder. The lens may change its focal length by its own
weight during a long exposure if the lens is used at a high upward or downward
angle with a focal length other than 24mm.
• The lens can be used at 24mm setting for picture taking even when locked by the
switch.
LENS HOOD (Ref. Figs. 1, 9 & 11)
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. Fig 9 & 10)
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 onto
the hood attaching bayonet ring (Fig. 9) and then rotate it clockwise to secure. The lens
hood will be secure when the mark “TAMRON O” is at the top (Fig. 10). 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 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 11)
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. (3)
Turn the hood clockwise until the alignment mark is at the top to set it. (Fig. 11)
