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.

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.
Blændeområde:
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.

Opbevaring:
- Opbevar linsen et køligt, tørt sted væk fra direkte sollys og ekstreme temperaturer.

- Consider using a lens pouch or case for added protection during transport.
Fejlfinding
Almindelige problemer:
- 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.
- Objektivet sidder ikke ordentligt fast: Ensure the red index marks are aligned correctly and the lens is rotated until it clicks. Do not force the lens.
