Product Usage Instructions

1. Attaching/detaching the lens:
2. Remove the rear and front lens caps and the camera body cap.
3. Align the white dot on the lens barrel with the white dot on the camera (mounting index), then insert the lens into the camera mount and rotate it clockwise until it locks.
4. Do not press the lens release button on the camera when mounting the lens.
5. Do not mount the lens at an angle.
6. Attaching the lens hood: It is recommended to use a lens hood to reduce flare and ensure maximum image quality.
7. Align the red line on the lens hood with the red line on the lens (lens hood index).
8. Insert the lens hood into the lens mount and rotate it clockwise until it clicks into place.
9. Ensure that the red dot on the lens hood is aligned with the red line on the lens (lens hood index).
10. Notes on use:
    • When carrying a camera with the lens attached, always firmly hold both the camera and the lens.
    • The lens is not waterproof. Keep water drops away from the lens when using it in the rain.
    • Do not touch the lens contacts.
11. Precautions on using a flash:
    • You cannot use a built-in camera flash with this lens. Use an external flash (sold separately).
    • When shooting close to a subject, use an external macro flash (sold separately).
12. Vignetting: When using the lens, the corners of the screen may become darker than the center. To reduce this phenomenon (called vignetting), close the aperture by 1 to 2 stops.

Attaching/detaching the lens

To attach the lens (See illustration B–1.)

1. Remove the rear and front lens caps and the camera body cap.
   • You can attach/detach the front lens cap in two ways, (1) and (2). When you attach/detach the lens cap with the lens hood attached, use method (2).
2. Align the white dot on the lens barrel with the white dot on the camera (mounting index), then insert the lens into the camera mount and rotate it clockwise until it locks.
   • Do not press the lens release button on the camera when mounting the lens.
   • Do not mount the lens at an angle.

To remove the lens  (See illustration B–2.)

• While holding down the lens release button on the camera, rotate the lens counterclockwise until it stops, then detach the lens.

Attaching the lens hood

• It is recommended that you use a lens hood to reduce flare and ensure maximum image quality.
• Align the red line on the lens hood with the red line on the lens (lens hood index), then insert the lens hood into the lens mount and rotate it clockwise until it clicks into place and the red dot on the lens hood is aligned with the red line on the lens (lens hood index).
• When using an external flash (sold separately), remove the lens hood to avoid blocking the flash light.
• When storing, fit the lens hood onto the lens backwards.

Focusing

• There are three ways to focus.

Auto focus

• The camera focuses automatically.

DMF (Direct manual focus)

• After the camera focuses in auto focus, you can make a fine adjustment manually.

Manual focus

• You focus manually.
• The focus mode of this lens cannot be switched with some camera models.
• For further information on compatibility, visit the web site of Sony in your area, or consult your dealer of Sony or local authorized service facility of Sony.

To switch AF (auto focus)/MF (manual focus)

• The focus mode can be switched between AF and MF on the lens.
• For AF photography, both the camera and lens should be set to AF. For MF photography, either or both the camera or lens should be set to MF.

To set the focus mode on the lens (1)

• AF: Set the focus ring to the X position.
• MF: Set the focus ring to the Y position.
• Refer to the camera manuals to set the focus mode of the camera.
• In MF, turn the focusing ring to adjust the focus (2) while looking through the viewfinder, etc. The distance scale is only a rough guide.
• When you move the focus ring from AF mode X to MF mode Y , focus is adjusted to the distance indicated on the distance scale.
• To use a camera equipped with an AF/MF control button
• Press the AF/MF control button to switch AF to MF when both the camera and lens are set to AF.
• Press the AF/MF control button to switch MF to AF when the camera is set to MF and the lens is set to AF.

Using the shake compensation function

Shake compensation switch

• ON: Compensate for camera shake.
• OFF: Does not compensate for camera shake. We recommend setting the shake compensation switch to OFF when shooting with a tripod.

Using focus-hold buttons

• The focus-hold button of this lens does not function with some camera models.
• For further information on compatibility, visit the web site of Sony in your area, or consult your dealer of Sony or local authorized service facility of Sony.
• Press the focus-hold button in AF to cancel AF. The focus is fixed and you can release the shutter on the fixed focus. Release the focus-hold button while pressing the shutter button halfway to start AF again.

Switching focus range (AF range)

• The focus-range limiter enables you to reduce the auto focusing time. This is useful when the subject distance is definite.
• Slide the focus-range limiter to select the focus range.
• FULL: AF is set to the minimum focusing distance to infinity.
• 0.5m: AF is set to 0.5 m (1.64 feet) to infinity. ˎ 0.5m-0.28m: AF changes from 0.5 m (1.64 feet) to the minimum focus length.*
• Depending on the camera model, AF may be set to the same focus range as when setting the focus-range limiter to FULL. For further information on compatibility, visit the web site of Sony in your area, or consult your dealer of Sony or local authorized service facility of Sony.

Macro photography

Magnification ratios

• The magnification scale is located on the distance scale.
• As the magnification increases, the camera is more vulnerable to shaking. Use a tripod to steady the camera when shooting.

Precautions on using a commercially available exposure meter or manual flash shooting function

• When shooting close to a subject, the brightness of the lens is reduced.
• When shooting in automatic exposure mode or metered manual mode (for example, the camera’s AUTO mode), the exposure is adjusted automatically. When using a commercially available exposure meter or shooting with the manual flash function available on some external flash units, set the exposure higher than the indicated value. (For information on the exposure compensation, refer to the exposure compensation table H.)
