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

Lets you smoothly and easily shift focus from one subject to another
This function allows you to shift focus at a preset speed, as is frequently done when recording video. Get exactly the kind of visual expression you want, for example, by slowly shifting the focus from a distant subject to one closer to you, or by guiding the gaze of the person viewing the video. Use the Focus Set Button to record two preset focal points in advance. Afterwards, a simple press on the Focus Set Button allows you to shoot while moving focus automatically and at a set speed; you don't have to worry about the speed blur associated with manual focus, and you can achieve stable visual expression.

Move focus to a prerecorded focal point with one press
This function allows you to preset focal points, for example, to deliberately defocus a subject during a video transition or to access a focal point for night photography. You can set the focus movement speed when recording video. You can also set focus on a preset focal point at maximum speed with a single press when taking still photographs. This feature broadens the range of your visual expression.

[MF Method]
This function adjusts focus movement when using manual focus. You can choose between "Non-linear," where the amount of focal point movement changes based on how fast you rotate the focus ring, and "Linear," where the focal point moves based on how much you rotate the focus ring. Some lenses allow users to adjust rotation as well, to offer more personalization.

A 9-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening even when stopped down by two stops from the wide-open aperture. This produces a smooth-edged bokeh in background highlights.

For greater protection when shooting outdoors, leak-resistant seals throughout the lens barrel help protect your equipment. Also, the Connector Port is the water-proofed USB Type-C variety.

TAMRON has long been an innovator of coating technologies that prevent ghosting and flare. Second-generation BBAR-G2 Coating is a groundbreaking advancement that provides vastly improved performance compared to the original BBAR (Broad-Band Anti-Reflection) Coating. The coating corrects for ghosting and flare to an unprecedented extent and renders fine subject detail with true clarity and stunning contrast even under backlit conditions.

The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture, and fingerprints.
