Setup
Mounting the Lens
- Ensure your camera is turned off and the battery is removed.
- Remove the rear lens cap and the camera body cap.
- Align the red index mark on the lens with the red index mark on the camera body.
- Insert the lens into the camera mount and turn it clockwise until it clicks into place. Do not force the lens.
- Replace the camera battery and turn on the camera.
Initial Checks
- Verify the lens is securely attached to the camera body.
- Check that the camera recognizes the lens by viewing the aperture display.
- Ensure the focus mode switch on the lens (if present) is set to 'AF' for autofocus operation.
Operating the Lens
Focusing
This lens features an Auto Focus (AF) mechanism. To use autofocus:
- Set the AF/MF switch on the lens to 'AF'.
- Half-press the camera's shutter button to activate autofocus. The camera will automatically adjust the focus.
- For manual focus (MF), set the switch to 'MF' and rotate the focusing ring on the lens until the subject appears sharp in the viewfinder.
Zooming
To change the focal length, rotate the zoom ring on the lens. The lens offers a focal range from 35mm (wide-angle) to 80mm (telephoto). Rotate the ring towards 35mm for a wider field of view and towards 80mm to magnify your subject.
Aperture Control
The aperture (f/4.0-5.6) is controlled electronically by the camera body. Select your desired shooting mode (e.g., Program AE, Shutter-priority AE, Aperture-priority AE, Manual) on your camera, and the camera will manage the aperture settings or allow you to set them manually depending on the mode.
Maintenance
Cleaning the Lens
- Lens Surface: Use a lens blower to remove dust and loose particles. For smudges or fingerprints, use a clean, soft lens cloth and a small amount of lens cleaning fluid. Apply the fluid to the cloth, not directly to the lens.
- Lens Body: Wipe the lens body with a soft, dry cloth. Avoid using organic solvents or strong cleaning agents.
Storage
- Always attach the front and rear lens caps when the lens is not in use.
- Store the lens in a cool, dry, and well-ventilated area, away from direct sunlight and high humidity.
- Avoid storing the lens with mothballs or chemicals that can emit volatile gases, as these can damage the lens elements.
