3. Setup

3.1 Attaching the Lens

1. Ensure both the camera and lens are powered off.
2. Remove the rear lens cap from the lens and the body cap from the camera.
3. Align the mounting index (usually a white dot) on the lens barrel with the corresponding index on the camera body.
4. Insert the lens into the camera's lens mount and rotate it clockwise until it clicks into place. Do not force the lens.

3.2 Removing the Lens

1. Ensure the camera is powered off.
2. While pressing the lens release button on the camera body, rotate the lens counter-clockwise until it detaches.
3. Attach the rear lens cap to the lens and the body cap to the camera to protect them from dust.

4. Operating the Lens

4.1 Autofocus (AF)

The lens is equipped with an Ultrasonic Silent Drive (USD) motor for fast and quiet autofocus. To use autofocus, set the AF/MF switch on the lens barrel to 'AF'.

The lens also features a focus limiter switch to optimize autofocus speed by restricting the focus range. The available settings are:

• FULL (0.3m - ∞): Uses the full focus range.
• 0.5m - ∞: Limits focus to subjects further than 0.5 meters (approximately 1.64 feet). Useful for general photography to prevent hunting in the macro range.
• 0.3m - 0.5m: Limits focus to subjects between 0.3 meters (approximately 11.8 inches) and 0.5 meters. Ideal for dedicated macro shooting.

4.2 Manual Focus (MF)

To use manual focus, set the AF/MF switch on the lens barrel to 'MF'. Rotate the focus ring to adjust focus. This lens supports full-time manual focus override, allowing you to fine-tune focus manually even when the lens is set to AF mode, without needing to switch modes.

4.3 Vibration Compensation (VC)

The Vibration Compensation (VC) mechanism helps reduce camera shake, allowing for sharper images when shooting handheld, especially in lower light conditions or at slower shutter speeds. To activate VC, set the VC switch on the lens barrel to 'ON'. Turn VC 'OFF' when using a tripod or when shooting at very fast shutter speeds where stabilization is not required.

4.4 Macro Photography

This lens offers a true 1:1 magnification ratio, meaning subjects can be reproduced at life-size on the camera's sensor. The minimum focusing distance is approximately 0.3 meters (11.8 inches), allowing for close-up photography of small subjects. For optimal macro results, consider using the focus limiter switch to the '0.3m - 0.5m' range.

5. Maintenance

Proper maintenance ensures the longevity and performance of your lens.

• Cleaning the Lens: Use a soft, clean microfiber cloth specifically designed for optical surfaces to gently wipe dust and smudges from the lens elements. For stubborn marks, use a small amount of lens cleaning fluid applied to the cloth, not directly to the lens.
• Body Cleaning: Wipe the lens barrel with a soft, dry cloth. Avoid using harsh chemicals or solvents.
• Moisture Protection: While the lens features moisture-resistant construction, it is not waterproof. Avoid exposing the lens to heavy rain or direct water spray. If the lens gets wet, wipe it dry immediately.
• Storage: Store the lens in a cool, dry place away from direct sunlight and extreme temperatures. Use front and rear lens caps to protect the elements. If storing for an extended period, consider using a desiccant to prevent mold growth.

6. Troubleshooting

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

• Autofocus Hunting: In very low light conditions or with subjects lacking contrast, the autofocus may struggle to lock. Try switching to manual focus or using a focus assist light. Ensure the focus limiter switch is set appropriately for your subject distance.
• Unsharp Images: Check that the lens is securely mounted to the camera. Verify that the focus mode (AF/MF) and VC switch are set correctly for your shooting situation. Ensure your shutter speed is fast enough to prevent motion blur, especially when not using VC.
• Lens Not Recognized: Ensure the lens is properly attached and the camera is powered on. Clean the electrical contacts on both the lens and camera body with a clean, dry cloth.

For persistent issues, consult the camera's instruction manual or contact Tamron customer support.
