Tamron 28-75mm f/2.8 Di III VXD G2 Lens (Sony E, A063)

The Tamron 28‑75mm f/2.8 Di III VXD G2 (Model A063) is an advanced standard‑zoom lens engineered for Sony E‑mount full‑frame mirrorless cameras. As a second‑generation upgrade over Tamron’s previous 28‑75mm design, this G2 version features a completely reworked optical formula, significantly faster autofocus, improved close‑range performance and refined handling — all while maintaining a compact, travel‑friendly form factor.

Key Capabilities

Constant Bright f/2.8 Aperture
The lens maintains a wide f/2.8 maximum aperture throughout the zoom range, enabling superior control over depth of field, excellent low‑light performance and smooth background separation.

Wide‑to‑Standard Zoom Range
The 28–75mm focal length offers versatile coverage for everyday photography: wide enough for landscapes and environmental shots, and long enough for portraits and street shooting.

Enhanced Close‑Focus Performance
With a minimum focus distance of 0.18 m (7.1 in) throughout the zoom range and an impressive maximum magnification ratio (~0.37×), this lens delivers close‑up capability that’s notably stronger than its predecessor, making it suitable for creative detail work.

Optical and Autofocus Technology

High‑Resolution Design
The optical construction features multiple specialized elements such as Low Dispersion and Aspherical glass to control aberrations, maintain edge‑to‑edge sharpness and ensure consistent image quality across all focal lengths.

VXD Linear Motor Autofocus
Equipped with Tamron’s VXD (Voice‑coil eXtreme‑torque Drive) AF system, the lens delivers ultra‑fast, highly accurate, and near‑silent autofocus — especially beneficial for moving subjects and video recording.

Smooth Manual Focus Override
Full‑time manual focus override lets photographers instantly fine‑tune focus without switching out of autofocus mode, offering greater creative control.

Build, Handling and Design

Compact and Lightweight
Despite its advanced optics and performance, the A063 remains compact and easy to carry, making it a perfect everyday partner for travel, street, portraiture and more.

Ergonomic Control Rings
Precision‑tuned focus and zoom rings offer smooth, predictable operation with a satisfying mechanical feel.

Durability
Moisture‑resistant construction and a fluorine‑coated front element help protect against dust, moisture and fingerprints — ideal for working in diverse environments.

67 mm Filter Thread
A standard 67 mm filter size allows easy use of filters across multiple lenses in your kit.
