Stowing lens hood on the lens (Ref. Fig. 9)

1. Reverse the lens hood. Point the lens toward the opening, then align the hood attach-
ment mark on the lens with the (TAMRON O) alignment on the hood (3).
2. Turn the hood clockwise until its alignment mark is at the top to set it. (Fig. 9, 2)

PRECAUTIONS IN SHOOTING

The optical design for Di-II takes into consideration the various features of digital sin-

gle reflex cameras. However, due to the configuration of the digital SLR cameras, even when
the Autofocus accuracy is within specifications, the focal point may be a little forward or
behind the optimum point when shooting with auto focus under some conditions.

The image circles of Di-II lenses are designed to match the digital SLR cameras using

the image sensors equivalent to APS-C (approx. 15.5 x 23.2mm). Do not use Di-II lenses with
such cameras may cause vignetting on the image.

A13  employs 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 the built-in flash on the camera is used, adverse photographic phenomena

such as corner illumination, fall-off, or vignetting at the bottom part of the image may be
observed, especially with wide angle ranges. This is due to the inherent limitation of the
coverage of the built-in flash, and/or the relative position of the flash to the edge of the lens
barrel which causes shadows on the image. It is strongly recommended to use a suitable
separate flash unit provided by the camera manufacturer for all flash photography.

When using the lens in the telephoto focal range, please be careful with the camera

shake. Effective way to avoid the camera shake is using an ISO setting of higher numbers.
Using a tripod or monopod is also effective.

When set on AF mode, interfering with the focusing ring may cause serious damage

to the lens mechanism.

Certain camera models may indicate the maximum and minimum aperture values of

the lenses appropriate numbers. This is inherent to the design of the camera and not an
indication of error.

When using a special filter such as a PL filter on the A16, use low-profile filters. The

thick rim of a normal filter may cause vignetting.
