2. Once unlocked, carefully remove the lens from the camera body.
3. Attach the rear lens cap to the lens and the body cap to the camera to protect them from dust and damage.

5. Operating the Lens

5.1 Autofocus (AF) and Manual Focus (MF)

The lens features an AF/MF switch to select your desired focusing mode:

• AF (Autofocus): Set the switch to 'AF' for automatic focusing. The Ultrasonic Silent Drive (USD) motor provides fast, precise, and quiet autofocus performance.
• MF (Manual Focus): Set the switch to 'MF' to manually adjust focus using the focus ring. This mode allows for fine-tuned focusing control.

5.2 Vibration Compensation (VC)

The Vibration Compensation (VC) mechanism helps reduce camera shake, allowing for sharper images when shooting handheld, especially in low light or at slower shutter speeds. The VC system in this lens offers a CIPA image stabilization performance level of 5 stops.

• VC ON: Set the VC switch to 'ON' to activate image stabilization.
• VC OFF: Set the VC switch to 'OFF' when using a tripod or when image stabilization is not desired.
• VC Auto Detect Mode 2: This lens features an advanced VC system that automatically detects panning motion, optimizing stabilization for such shots.

5.3 Zooming

To change the focal length, rotate the zoom ring. The lens allows for smooth adjustment between 24mm (wide-angle) and 70mm (short telephoto). The focal length markings on the ring provide a visual guide.

5.4 Lens Lock Mechanism

The lens is equipped with a lock switch to prevent the lens barrel from extending unintentionally, particularly when carrying the camera with the lens attached. This lock is effective only at the 24mm wide-angle position.

• To Lock: Rotate the zoom ring to the 24mm position and slide the lock switch to the 'LOCK' position.
• To Unlock: Slide the lock switch back to the 'UNLOCKED' position.

6. Maintenance and Care

6.1 Cleaning the Lens

Keep your lens clean to maintain optimal image quality:

• Use a blower brush to remove dust and loose particles from the lens surfaces.
• For smudges or fingerprints, use a clean, soft microfiber lens cloth and a small amount of lens cleaning solution. Apply the solution to the cloth, not directly to the lens.
• Clean the lens mount contacts with a dry, clean cloth if they appear dirty.

6.2 Storage

When not in use, store the lens with both front and rear caps attached. Keep it in a protective case or bag, away from dust, moisture, and extreme temperatures. If storing for extended periods in humid conditions, consider using a desiccant to prevent mold growth.

6.3 Fluorine Coating

The front element of this lens features a fluorine coating, which repels water and oil, making it easier to wipe away smudges, fingerprints, and dirt. This contributes to easier maintenance and improved durability.

6.4 Moisture-Resistant Construction

The lens incorporates moisture-resistant construction, providing enhanced protection against dust and moisture ingress. This makes the lens more reliable for outdoor photography in various weather conditions, though it is not fully waterproof.

7. Troubleshooting

If you encounter issues with your lens, consider the following common solutions:

• Autofocus Not Working:
  • Ensure the AF/MF switch on the lens is set to 'AF'.
  • Check that the camera's focus mode is set to AF.
  • Clean the electrical contacts on both the lens and camera body.
• Vibration Compensation Not Effective:
  • Ensure the VC switch on the lens is set to 'ON'.
  • VC is most effective for static subjects; extreme camera shake or very long exposures may still result in blur.
• Lens Not Attaching/Detaching Smoothly:
  • Ensure proper alignment of the mount index marks.
  • Do not force the lens. If resistance is met, re-align and try again.
• Image Quality Issues (e.g., soft images, flare):
  • Ensure the lens elements are clean.
  • Use the included lens hood to minimize flare, especially when shooting towards bright light sources.
  • Check your camera's settings (e.g., ISO, shutter speed, aperture) for appropriate exposure.

If problems persist after attempting these solutions, please contact Tamron customer support or a qualified service technician.
