3. Setup

3.1 Attaching the Lens

1. Ensure your camera is turned off.
2. Align the mounting index mark on the lens (usually a red dot or white square) with the corresponding mark on your camera's lens mount.
3. Insert the lens into the camera mount and rotate it clockwise until it clicks into place. Do not force the lens.

3.2 Detaching the Lens

1. Ensure your camera is turned off.
2. While pressing the lens release button on your camera, rotate the lens counter-clockwise until it stops.
3. Carefully remove the lens from the camera body.

3.3 Attaching the Lens Hood

The included flower-shaped lens hood helps to block unwanted stray light and protect the front element of the lens. Align the lens hood with the front of the lens and rotate it until it locks into position. For storage, the hood can be reversed and attached to the lens.

4. Operating the Lens

4.1 Autofocus (AF) / Manual Focus (MF) Switch

Locate the AF/MF switch on the side of the lens barrel. Slide the switch to 'AF' for autofocus operation or 'MF' for manual focus. In AF mode, you can still fine-tune focus manually without switching to MF, thanks to the full-time manual focusing capability.

4.2 Vibration Compensation (VC) Switch

The VC switch is also located on the lens barrel. Set it to 'ON' when shooting handheld to activate image stabilization. Turn it 'OFF' when the camera is mounted on a tripod or when using very fast shutter speeds, as VC can sometimes interfere with stability in these situations.

4.3 Zooming

Rotate the zoom ring to adjust the focal length between 24mm and 70mm. The current focal length is indicated on the lens barrel.

4.4 Manual Focusing

In MF mode, rotate the focus ring to achieve sharp focus. The distance scale on the lens barrel provides an indication of the current focus distance.

5. Maintenance

5.1 Cleaning the Lens

• Use a blower brush to remove dust from the lens surfaces.
• For smudges or fingerprints, use a clean, soft microfiber cloth specifically designed for optics, along with a small amount of lens cleaning fluid. Apply the fluid to the cloth, not directly to the lens.
• Never use abrasive materials or harsh chemicals to clean the lens.

5.2 Storage

• Store the lens with both front and rear caps attached to protect the elements from dust and scratches.
• Keep the lens in a cool, dry place, away from direct sunlight and extreme temperatures or humidity.
• If storing for extended periods, consider using a dehumidifying cabinet to prevent mold growth.

6. Troubleshooting

6.1 Blurry Images

• Check if the lens is properly focused. Ensure the AF/MF switch is in the desired position.
• If shooting handheld, ensure the VC switch is 'ON'.
• Verify that your camera's shutter speed is appropriate for the lighting conditions and focal length to avoid motion blur.
• Clean the lens elements if smudges or dust are present.

6.2 Autofocus Not Working

• Ensure the AF/MF switch on the lens is set to 'AF'.
• Check your camera's focus mode settings.
• Ensure there is sufficient light and contrast in your subject for the autofocus system to lock on.
• Confirm the lens is securely attached to the camera body.

6.3 Lens Not Attaching/Detaching Smoothly

• Ensure the camera is turned off before attempting to attach or detach the lens.
• Align the mounting marks correctly. Do not force the lens.
• Check for any obstructions or debris on the lens mount or camera mount.
