• Ndozi akwụkwọ ntuziaka (MF): Set the Focus Mode Switch to 'MF'. Rotate the focus ring on the lens to manually adjust focus.

5.2 mbugharị

Rotate the zoom ring to adjust the focal length from 100mm (wide-angle telephoto) to 400mm (super telephoto). The lens barrel will extend as you zoom towards 400mm.

5.3 Optical Stabilization (OS)

The Optical Stabilizer helps reduce camera shake, especially at longer focal lengths or slower shutter speeds.

• Gbanyụọ: Disables optical stabilization.
• Edị 1: Suitable for general photography, compensating for vertical and horizontal camera shake.
• Edị 2: Ideal for panning shots, compensating for vertical camera shake while allowing horizontal movement.

5.4 AFL Button

The AFL (Autofocus Lock) button can be assigned various functions through your camera's custom settings menu. Refer to your camera's instruction manual for available customization options.

5.5 Zoom Lock

To prevent the lens barrel from extending unintentionally during transport or when pointing the camera downwards, slide the Zoom Lock Switch to the 'LOCK' position when the lens is set to 100mm.

7.1 Autofocus Not Working

• Ensure the Focus Mode Switch on the lens is set to 'AF'.
• Check your camera's focus settings to ensure autofocus is enabled.
• Verify that the lens is securely mounted to the camera body.
• In very low light conditions or with low-contrast subjects, autofocus may struggle. Try switching to manual focus or using an external light source.

• Check if the Optical Stabilizer (OS) is enabled (Mode 1 or Mode 2) if shooting handheld, especially at longer focal lengths.
• Ensure your shutter speed is fast enough to prevent motion blur, particularly with moving subjects.
• Verify that the lens and camera sensor are clean.
• Confirm that the lens is properly focused on your subject.

7.3 Lens Creep
