Tamron 28-75mm F/2.8 Di III VXD G2 Lens - Sony E-mount

The filter size is 67mm.

No, this lens does not have built-in image stabilization. It relies on in-body image stabilization (IBIS) found in some Sony cameras.

The closest focusing distance is 0.18m (7.1 in) at the 28mm end.

While the lens can physically mount on Sony APS-C cameras, the 28-75mm range will result in a different equivalent focal length due to the crop factor. The lens is optimized for full-frame cameras.

The lens incorporates LD (Low Dispersion) and GM (Glass Molded Aspherical) lens elements to minimize aberrations.

You can update the lens firmware using the Tamron Lens Utility software and a compatible USB-C cable. Refer to the Tamron website for instructions and the latest software.

Ensure the lens is set to AF mode on both the lens and camera. Clean the lens contacts and check the camera's focus settings.

Check if the focus is accurate by using the focus ring or the autofocus system. Ensure the lens is clean and that the camera's shutter speed is sufficient to avoid motion blur.

Make sure the lens is properly mounted on the camera. Check the camera and lens firmware for updates.

Enable in-camera lens corrections in your Sony camera settings to correct for distortion. You can also correct distortion in post-processing using editing software.
