Mounting and Dismounting the Lens

To remove the lens, rotate the lens counter-clockwise while pressing the lens release button on the camera.

Important: Turn off the camera power before mounting or dismounting the lens. Refer to your camera's owner's manual for detailed instructions.

Focus Switching Mode

Select the desired focus mode on the camera. For manual focusing, rotate the focus ring 6 to achieve the desired focus. Refer to your camera's owner's manual for details.

Note: In AF mode, automatic focusing may be difficult depending on the subject.

Connector Port (Fig. 1)

Connect the connector port 10 to a computer using a TAMRON connection cable (sold separately) and use the dedicated application "TAMRON Lens Utility™" to customize the focus ring and update firmware.

For more information, refer to the online help for "TAMRON Lens Utility™" at: https://www.tamron.jp/en/support/lensutility/help/

• The TAMRON connection cable (sold separately) should only be used to connect TAMRON lenses equipped with a connector port to a computer.
• Tamron is not responsible for any data loss or damage incurred when using the TAMRON connection cable (sold separately).

Zooming (Fig. 1)

Rotate the zooming ring 7 to adjust the focal length (zooming position) to the desired setting.

Lens Hood (Fig. 1, 2, 3)

The lens hood can reduce scattered light that may affect the image.

Using the Lens Hood (Fig. 2)

Align the hood mounting compatibility mark 2 with the hood release mark 5 on the lens. Rotate the hood 1 in the direction of the arrow until the hood lock mark 3 aligns with the hood release mark 5.

Securing the Lens Hood (Fig. 3)

Attach the hood 1 in reverse and rotate until it locks into place.

Note: If the hood is not attached correctly, the periphery of the captured image may be darkened.

Precautions for Use

• The internal focusing (IF) system is used to reduce the minimum focusing distance. Therefore, the angle of view may be wider than lenses using other focusing systems when shooting at distances less than infinity.
• The lens hood or lens barrel may block flash light. Test shooting is recommended initially.
• Due to the display systems of different cameras, values displayed may differ from the maximum and minimum aperture values indicated in the specifications. This does not indicate a malfunction.
• Do not touch the lens-camera interface contacts 12 with your fingers. Doing so may cause malfunctions.
• Condensation may form due to sudden temperature changes, causing malfunctions.
• The front lens element has a coating for protection against dirt. After dust is removed from the lens surface with a blower or other method, wipe the surface with a dry cloth.
• Never use benzene, thinner, or other organic solvents to clean the lens.
• Store the lens in a clean, well-ventilated place.
