Setup
Attaching the Lens:
- Align the red index mark on the lens with the red index mark on your Canon EOS camera body.
- Rotate the lens clockwise until it clicks into place.
Detaching the Lens:
- While pressing the lens release button on the camera body, rotate the lens counter-clockwise until it stops.
- Remove the lens from the camera body.
Always attach the rear lens cap when the lens is not mounted on the camera to protect the rear element and electrical contacts.
Operating
Autofocus (AF) / Manual Focus (MF) Switch:
The lens features an AF/MF switch. Set the switch to 'AF' for automatic focusing or 'MF' for manual focusing. In AF mode, the lens will automatically adjust focus when the shutter button is half-pressed. In MF mode, you can manually rotate the focusing ring to achieve desired focus.
Focal Length Adjustment:
Rotate the zoom ring on the lens to adjust the focal length between 28mm (wide-angle) and 80mm (telephoto). This allows for flexibility in framing your shots without changing lenses.
Aperture Range:
The lens has a variable aperture of F/3.5-5.6, meaning the maximum aperture changes with the focal length. At 28mm, the maximum aperture is F/3.5, and at 80mm, it is F/5.6. This affects the amount of light entering the lens and the depth of field in your images.
Minimum Focusing Distance:
The minimum focusing distance for this lens is 0.38 meters (approximately 15 inches), allowing for close-up shots of subjects.
Maintenance
Cleaning the Lens:
- Use a lens blower to remove dust and loose particles from the lens surface.
- For smudges or fingerprints, use a soft, clean microfiber cloth specifically designed for lenses, along with a small amount of lens cleaning solution.
- Never use abrasive materials or harsh chemicals on the lens.
Storage:
- Store the lens in a cool, dry place away from direct sunlight and extreme temperatures.
- Always attach the front and rear lens caps when not in use to protect the glass elements.
- Consider using a lens pouch or case for added protection during transport.
Troubleshooting
Common Issues:
- Focusing Problems: Ensure the AF/MF switch is set correctly. Check if there is enough light for the autofocus system to work effectively. In low light, switch to MF.
- Dust or Smudges on Images: Clean the lens elements as described in the Maintenance section. If the issue persists, it might be dust on the camera sensor, which requires professional cleaning.
- Lens Not Attaching Securely: Ensure the red index marks are aligned correctly and the lens is rotated until it clicks. Do not force the lens.
