3. Attaching the Lens Hood
The included lens hood helps to prevent flare and protect the front element of the lens. Align the red dot on the lens hood with the red dot on the front of the lens, then twist the hood clockwise until it locks into position. To store, you can reverse the hood and attach it to the lens in the same manner.

Operating the Lens
1. Focus Modes (AF/MF Switch)
This lens features an AF/MF switch on the barrel. Slide the switch to 'AF' for autofocus operation, allowing the camera to automatically focus on your subject. Slide it to 'MF' for manual focus, enabling precise focus adjustments using the focus ring.
2. Zooming
The zoom ring is located towards the front of the lens barrel. Rotate the zoom ring to adjust the focal length between 24mm (wide-angle) and 70mm (telephoto). The focal length markings are clearly indicated on the lens.
3. Aperture Control
The lens features a constant maximum aperture of F2.8 across the entire zoom range. Aperture can be controlled via your camera body's settings. This wide aperture is ideal for low-light conditions and achieving shallow depth of field.
4. Using the Focus Hold Button
The lens is equipped with a customizable focus hold button. By default, pressing this button locks the focus at the current distance. This function can often be re-assigned to other camera functions through your camera's menu system.
Maintenance
1. Cleaning the Lens
To clean the lens surface, use a soft, lint-free cloth specifically designed for optical surfaces. For stubborn smudges, a small amount of lens cleaning solution applied to the cloth (not directly to the lens) can be used. Avoid touching the glass elements with your fingers.
2. Storage
When not in use, always attach the front and rear lens caps. Store the lens in its provided case or a dry, cool place away from direct sunlight and extreme temperatures. Avoid storing the lens in areas with high humidity to prevent mold growth.
3. Environmental Considerations
This lens is designed with a dust and splash-resistant structure. However, it is not waterproof. Avoid exposing the lens to heavy rain, snow, or direct water spray. Rapid changes in temperature can cause condensation inside the lens; allow the lens to accilmate gradually when moving between environments with significant temperature differences.
Troubleshooting
If you encounter issues with your lens, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lens not focusing (Autofocus) | AF/MF switch set to MF; insufficient light; subject too close; camera settings. | Set AF/MF switch to AF. Ensure adequate lighting. Check minimum focusing distance. Verify camera's focus mode and settings. |
| Image quality is poor/blurry | Lens dirty; camera shake; incorrect focus; aperture too wide/narrow. | Clean lens elements. Use a faster shutter speed or tripod. Re-focus. Adjust aperture for desired depth of field and sharpness. |
| Lens not recognized by camera | Improper mounting; dirty electrical contacts; outdated camera firmware. | Re-mount the lens securely. Clean the lens and camera electrical contacts with a dry cloth. Check for camera firmware updates. |
