APERTURE ADJUSTING AND AE SETTING
To set the aperture, rotate the aperture ring to the desired point on the aperture scale. The
AE mark of the aperture ring should be set in accordance with the instructions for the cam-
era in use.
ZOOMING
To set your lens to the desired image composition you desire, simply look through the
viewfinder and operate the zoom ring.
ANTI-SLIP MODE
Tamron AF28-105mm F/2.8 lens incorporates an "Anti-Slip" mechanism designed to let you
change the rotation torque of the zoom ring by pulling the ring toward the camera or push-
ing it the opposite way. By pulling the ring backward, you will see an imprint reading "Anti-
Slip Mode." In this position, the torque is heavier and prevents any sliding movement of the
zoom ring due to its weight balance when you carry your camera with the lens positioned
downward. When the zoom ring is pushed toward the subject, the imprint is hidden. In this
mode, the zoom torque is lighter, and is recommended for normal shooting conditions.
