LENS HOOD (Ref. Figs. 1, 5 & 7)
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.
Attaching the Lens Hood (Ref. Fig 5 & 6)
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. 5) and then rotate it clockwise to secure. The lens
hood will be secure when the mark “TAMRON O” is at the top (Fig. 6). 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 7)
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. 7)
PRECAUTIONS IN SHOOTING
-The optical design for Di-III takes into consideration the various features of digital
single reflex cameras. However, due to the configuration of the digital single reflex
cameras, even when autofocus accuracy is within specifications, the focal point may be a
little forward or behind the optimum point when shooting with autofocus under some
conditions.
-The Tamron lenses described here employ an internal focusing (IF) system. Because of
the characteristics of this optical design, the angles of view at distances other than infinity
are wider than that of the lenses applying an ordinary focusing system.
-When using the flash supplied with the camera, adverse photographic phenomena such
as corner illumination fall-off or vignetting at the bottom part of the image may be
observed, especially in wide angle ranges. This is due to the inherent limitation of the
supplied flash, and/or the relative position of the flash to the edge of the lens barrel which
causes shadows on the image. We also recommend removing the hood when using the
supplied flash.
-When set on AF mode, interfering with the focusing ring may cause serious damage to
the lens mechanism.
-When using a special filter such as a PL filter, use low profile filters. The thick rim of a
normal filter may cause vignetting.
TO ENSURE LONG-TERM SATISFACTION
-Avoid touching the glass element surface. Use a photographic lens cloth or blower to
remove dust from the lens element surface. When not using the lens, always place a lens
cap on it for protection.
-Use a lens cleaning tissue or lint cloth with a drop of cleaning solution to remove
fingerprints or dirt on the glass lens surface with a rotary motion from the center to the
edge.
- Use a silicon cloth to clean your lens barrel only.
-Mildew is an enemy of your lens. Clean the lens after shooting near water or in any
humid place. Store your lens in a clean, cool, dry place. When storing the lens in a lens
