2. Setup and Installation
2.1 Attaching the Lens
- Ensure the camera is powered off.
- Remove the rear lens cap and the camera body cap.
- Align the white mounting mark on the lens with the white mounting mark on the camera body.
- Insert the lens into the camera mount and rotate it clockwise until it clicks into place. Do not force the lens.
- Remove the front lens cap.
2.2 Attaching the Lens Hood
The lens hood helps to prevent stray light from entering the lens, reducing flare and ghosting. It also provides some protection for the front element.
- Align the mark on the lens hood with the mark on the front of the lens.
- Rotate the hood clockwise until it locks into position.
- To store, reverse the hood and attach it in the same manner.

3. Operating the Lens
3.1 Zooming
To adjust the focal length, rotate the zoom ring on the lens. The focal length markings (18, 23, 35, 55, 70, 100, 135mm) indicate the current setting. The lens extends as you zoom towards the telephoto end.

3.2 Focusing
The lens supports both autofocus (AF) and manual focus (MF). The focus mode is typically controlled via the camera body settings. In manual focus mode, rotate the focus ring to achieve sharp focus.
3.3 Optical Image Stabilization (OIS)
The OIS function helps to reduce blur caused by camera shake, especially useful in low light or when shooting at longer focal lengths. The OIS switch is located on the side of the lens barrel. Set it to ON to activate image stabilization, or OFF when using a tripod or when stabilization is not desired.
3.4 Aperture Control
The aperture is controlled electronically via the camera body. Refer to your camera's instruction manual for details on adjusting aperture settings.
4. Maintenance and Care
4.1 Cleaning the Lens
- Use a blower brush to remove dust and loose particles from the lens surfaces.
- For smudges or fingerprints, use a clean, soft microfiber cloth specifically designed for optical lenses, along with a small amount of lens cleaning fluid. Apply the fluid to the cloth, not directly to the lens.
- Clean the lens barrel with a soft, dry cloth. Do not use organic solvents like thinner or benzene.
4.2 Storage
- When not in use, attach both front and rear lens caps.
- Store the lens in a cool, dry place, away from direct sunlight and high humidity.
- If storing for extended periods, consider using a desiccant to prevent mold growth.
5. Troubleshooting
5.1 Common Issues and Solutions
| Issue | Possible Cause | Solution |
|---|---|---|
| Lens not attaching to camera | Incorrect alignment; obstruction | Ensure white marks are aligned and rotate until it clicks. Check for any debris in the mount. |
| Autofocus is slow or inaccurate | Low light conditions; dirty lens contacts; camera settings | Ensure sufficient light. Clean lens and camera contacts. Check camera's AF mode and settings. |
| Images are blurry | OIS off; camera shake; incorrect focus; dirty lens | Activate OIS. Use faster shutter speed or tripod. Re-focus. Clean lens elements. |
| Zoom ring is stiff | New lens; environmental factors | This can be normal for new lenses and may loosen with use. Avoid forcing the ring. |
