3. Setup

Attaching the Lens:

1. Ensure your camera is powered off.
2. Align the mounting index on the lens barrel with the mounting index on your camera body.
3. Rotate the lens clockwise until it clicks into place.

Detaching the Lens:

1. Press and hold the lens release button on your camera body.
2. Rotate the lens counter-clockwise until it detaches from the camera body.

Attaching the Lens Hood:

Align the lens hood with the front of the lens and rotate it clockwise until it locks securely. The lens hood helps to prevent stray light from entering the lens, reducing flare and ghosting.

Filter Installation:

The lens features a 67mm filter thread. To attach a filter, carefully screw it onto the front of the lens until it is snug. Avoid overtightening.

4. Operating Instructions

Zooming:

Rotate the zoom ring to adjust the focal length between 17mm and 28mm. The internal zoom mechanism ensures the lens length does not change during zooming.

Focusing:

• Autofocus (AF): The lens utilizes Tamron's RXD motor for fast, precise, and quiet autofocus. Ensure your camera is set to an AF mode. The lens supports advanced Sony AF features like Fast Hybrid AF and Eye AF.
• Manual Focus (MF): Switch your camera to MF mode. Rotate the focus ring to achieve desired sharpness.

Aperture:

This lens maintains a constant maximum aperture of f/2.8 throughout its zoom range, allowing for excellent low-light performance and creative depth-of-field control.

5. Maintenance

Cleaning the Lens:

The front surface of the lens has a protective coating, making it easy to wipe clean. Use a soft, lint-free cloth and a specialized lens cleaning solution. Avoid harsh chemicals or abrasive materials that could damage the coating.

Moisture Resistance:

The lens features a moisture-resistant construction. While designed to withstand light moisture, it is not waterproof. Avoid exposing the lens to heavy rain or submerging it in water. If the lens gets wet, wipe it dry immediately with a clean cloth.

Storage:

When not in use, store the lens with both front and rear caps attached in a dry, cool place away from direct sunlight and extreme temperatures. Using a lens pouch or case can provide additional protection.

6. Troubleshooting

Autofocus Issues:

• Ensure your camera is set to an appropriate AF mode and that the subject has sufficient contrast for the autofocus system to lock on.
• Check for any obstructions on the lens elements or camera sensor.
• In very low light conditions, autofocus may be slower. Consider switching to manual focus or using an external light source.

Image Quality Concerns:

• Vignetting/Distortion: Some wide-angle lenses may exhibit minor vignetting or distortion, especially at their widest focal lengths. These are often correctable using in-camera lens correction settings or post-processing software (e.g., Adobe Lightroom, Capture One).
• Softness: Ensure proper focus. While the lens is designed for sharpness, extreme corners at the widest focal length might show slight softness, which is common for ultra-wide zooms.

Physical Issues:

• If the zoom or focus rings feel stiff or make unusual noises, do not force them. Contact Tamron customer support for assistance.
• Avoid dropping the lens. While durable, severe impacts can cause internal damage.
