INFRARED INDEX (Model A10 and 179D) It is necessary to adjust the focus point when using black and white infrared film with a red filter. This is normally done by focusing on the subject, reading the value from the distance scale, aligning that value with the infrared index and attaching the red filter.
  • Page 6: Lens Hood

    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.
  • Page 7 PRECAUTIONS IN SHOOTING Tamron AF 28 - 105 (Model 179D) employs an internal Focusing (IF) system to achieve a remarkable 0.5m (1.6 feet) M.O.D. (Minimum Object Distance) at 105mm. Because of the characteristics of this optical design, the 105mm coverage, at the distances other than infini- ty, is wider than that coverage of lenses using an ordinary focusing system.
  • Page 8 Do not use the lens hood when you shoot with your camera's built-in flash. Even with- out the lens hood, an arched-shape shadow may be observed at the bottom portion of the picture when using the built-in flash. Tamron recommends using an optional flash unit (clip- on grip type) when use of flash is necessary.
