Tamron 175D Specification - Canon / Minolta

APERTURE CONTROL & AE SETTING

Canon / Minolta

Your camera controls the aperture depending on the shooting mode in use. Although the

aperture value varies in accordance with zooming, the camera itself reads out the change to

provide automatic compensation.

Nikon / Pentax

When shooting in programmed AE or shutter-priority AE mode, rotate the aperture ring to

the minimum position. For aperture-priority or manual mode, turn the aperture ring to the

desired setting. In case of F401/F50 series models, the aperture is set by the camera in

accordance with the given camera instructions.

LENS HOOD

A bayonet-type lens hood is provided as a standard accessory. Tamron recommends shoot-

ing with the hood attached whenever possible as the lens hood cuts out light, which is

harmful to image quality. However, please be aware of the precautions noted below when

your camera is equipped with a built-in flash. When the hood is not in use, it can be placed

on the front of the lens in reverse:

Attaching the Lens Hood Align the index mark on the hood with the corresponding

index mark on the lens. Push the hood onto the lens and then rotate it clockwise to secure.

When attaching the lens hood, hold the focusing and zoom control rings so that they are

not rotated unintentionally.

TRIPOD SOCKET (Ref. Figs. 9 & 10)

To change the camera from horizontal to vertical position or vice versa, loosen the

locking knob for the tripod-attaching base by rotating it counterclockwise, then rotate lens

and the camera about the longitudinal axis of the lens. Tighten the locking knob by rotating

it in clockwise direction until it stops. (Fig. 9)

To remove the tripod-attaching base, loosen the locking knob, pull it back slightly, and

then lift the knob to open the tripod base ring as illustrated in Fig. 10. When removing the

tripod-attaching base, hold the lens and the camera securely to prevent them from both

accidentally falling.
