LENS HOOD (Ref. Figs. 1, 2, 9, 10 & 11)
A bayonet-type lens hood is provided as a standard accessory. 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. Fig 9 & 10)
Align the index mark on the hood with the corresponding index mark (or the top of the
index line of the distance scale) on the lens. Press the hood lightly onto the hood attaching
bayonet ring (Fig. 9, No. 1) and then rotate it clockwise to secure (Fig. 9, No. 2). The lens hood
will be securely held as the mark "TAMRON O" comes to the top (Fig. 10, No. 3). When attach-
ing 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 indices when using zoom lenses
including wide-angle (e.i. 35mm or wider) settings. Improper attachment of a hood for wide-
angle zoom lens may cause large shadowed areas in your pictures.
Stowing lens hood (Ref. Fig. 11)
a. Detach and reverse lens hood then, align alignment mark of lens hood (TAMRON O) with
alignment mark of lens. (Fig. 11a)
b.
Press lens hood evenly onto bayonet ring and turn hood clockwise until stop. When
stopped, alignment mark of hood will be placed at top. (Fig. 11b).
DEPTH OF FIELD
With camera equipped with a depth-of -field-preview button or an aperture-stop-
down mechanism, the depth of field can be directly observed on the viewfinder screen of
your camera. For the operational details, read the instruction manual of your camera.
* In case you need a depth-of-field table of your lens, please ask for it at a Tamron distribu-
tor or a service station.
INFRARED PHOTOGRAPHY
Please be aware that there is no infrared index line on any models listed on this owner's
manual, and therefore, practically, no black-and-white infrared film can be used with these
lenses.
