Trade Name: SONY
Model : SEL40F25G
Responsible Party: Sony Electronics Inc.
Address : 16535 Via Esprillo, San Diego, CA 92127 U.S.A.
Telephone Number: 858-942-2230
This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions:

1. This device may not cause harmful interference, and
2. this device must accept any interference received, including interference that may cause undesired operation.

• Do not leave the lens exposed to the sun or a bright light source. Internal malfunction of the camera body and lens, smoke, or a fire may result due to the effect of light focusing. If circumstances necessitate leaving the lens in sunlight, be sure to attach the lens caps.
• When shooting against the sun, keep the sun completely out of the angle of view. Otherwise, solar rays may be concentrated at a focal point inside the camera, causing smoke or a fire. Keeping the sun slightly out of the angle of view may also cause smoke or a fire.
• When carrying a camera with the lens attached, always firmly hold both the camera and the lens.
• This lens is not water-proof, although designed with dust-proofness and splash-proofness in mind. If using in the rain etc., keep water drops away from the lens.
• If the lens alone is shaken or if a camera with the lens attached is shaken while the camera is turned off, an internal component of the lens may rattle. This, however, does not indicate a malfunction. In addition, while you carry around the lens, your movement may cause the internal lens groups to shake. This, however, does not affect the performance of the lens groups.

Precautions on using a flash

• When using a flash, always remove the lens hood and shoot at least 1 m (3.3 feet) away from your subject.
• With certain combinations of lens and flash, the lens may partially block the light of the flash, resulting in a shadow at the bottom of the picture. In such a case, adjust the shooting distance before shooting.

Vignetting

• When using the lens, the corners of the screen become darker than the center. To reduce this phenomena (called vignetting), close the aperture by 1 to 2 stops.

Attaching and Detaching the Lens

To attach the lens (See Fig..)

1. Remove the rear lens cap and the camera body cap.
2. Align the white index on the lens barrel with the white index 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.
3. Remove the front lens cap.
   • You can attach/detach the front lens cap in two ways, (1) and (2).

To detach the lens

1. Attach the front lens cap.
2. While holding down the lens release button on the camera, rotate the lens counterclockwise until it stops, then detach the lens. (See Fig. .)

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.

• Be sure to rotate the lens hood until it clicks into place to prevent its disengagement from the lens.
• When using a built-in camera flash or an external flash (sold separately) attached to the camera, remove the lens hood to avoid blocking the flash light.
• When using the lens hood, attach the front lens cap over the lens hood.
• You can attach a filter over the lens hood. Depending on the type of filters, you can attach the lens hood after attaching a filter over the lens as well.

Focusing

• The focus mode switch 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.

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
Slide the focus mode switch to the appropriate mode, AF or MF (1).

• 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.

To use a camera equipped with an AF/MF control button

• By pressing the AF/MF control button during AF operation, you can temporarily switch to MF.
• Pressing the AF/MF control button during MF operation lets you temporarily switch to AF if the lens is set to AF and the camera to MF.

Using the 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.

Adjusting the Exposure

When you align "A" on the aperture scale to the aperture index, the exposure is set by the camera. And you can adjust the amount of light between f/2.5 and f/22 by rotating the aperture ring.

Adjust the amount of light manually

Rotate the aperture ring to the desired exposure (f-stop) when the camera is set to the M mode or A mode.

Notes: Set the aperture click switch to "OFF" when shooting movies. (See Fig..)
When the aperture click switch is set to "OFF," the sound of the aperture ring is reduced. (For movie recording)
If you change the aperture value while shooting a movie with the aperture click switch set to "ON," the sound of the aperture ring will be recorded.
