[. . . ] During AF operation, the focusing ring will rotate and its movement should not be hindered. Manual Focusing When the lens is used on a Nikon/Minolta/Pentax AF camera, switch the camera to the manual focus mode. When the lens is on a Canon EOS camera, set the lens AF/MF Switch to the "MF" mode. Turn the focusing ring while looking through the viewfinder.

The focus ring can only be turned between infinity and 1. 5m when the macro selector switch is set to the Normal position (when macro photography is cancelled. ) It cannot be turned to a distance closer than 1. 5m. The macro selector switch cannot be operated unless the focus ring is set to a distance between 1. 5m and infinity. Always make sure to set the focus ring between 1. 5m and infinity before operating the macro selector switch. 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 shooting 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. 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. 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. When removing the tripod-attaching base, hold the lens and the camera securely to prevent them from both accidentally falling. Fig. 9 Altering camera between vertical & horizontal positions 1. Loosen lock knob by rotating knob counterclockwise. Turn camera and lens so as position alignment marks meet each other.

[. . . ] Using high-speed film (ISO 400 or faster) with a fast shutter speed is also helpful to reduce the effect of camera shake. TO ENSURE LONG-TERM SATISFACTION Avoid touching the glass element surface. Use a photographic lens cloth or blower brush 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 edge. [. . . ]
