The 28-75mm F/2.8 Di III VXD G2 (model A063) is a fast standard zoom lens for mirrorless full format system cameras from Sony and the successor to the famous 28-75mm F/2.8 Di III RXD (model A036). A high resolution and outstanding image quality are among its most important innovations. The new lens has a revised optical system but is as compact as the previous model. To minimize aberrations, the optical structure includes LD (Low Dispersion) and GM (Glass Molded Aspherical) lens elements. The imaging performance is very high at every focal length and over the entire image area. When the aperture is open, there is a beautiful bokeh effect. With these and many other innovations, the 28- 75mm F/2.8 G2 is the first choice for everyone who wants to maximize their creativity.

Achievement of high image quality and resolving power while maintaining a compact, lightweight design.
It took a lot of work to improve the optical performance of the first-generation Model A036, which had an established reputation for outstanding image quality. TAMRON redesigned the 28-75mm F2.8 G2 optical system from the ground up, thereby attaining the stunning performance of a new fast-aperture zoom lens.
The 28-75mm F2.8 G2 retains its predecessor's lightweight, compact design while delivering sharp rendering to the corners of images across the entire zoom range. Check the MTF charts and actual photos to see how the Model A063 differs from the 1st-generation model.

MOD of 0.18m (7.1 in) at wide end and maximum magnification ratio of 1:2.7.
The Minimum Object Distance (MOD) of 0.19m (7.5 in) at the wide-end and maximum magnification ratio of 1: 2.9 that the 1st-generation Model A036 achieved have been well received because they allow users to enjoy close-up photography that emphasizes unique to wide-angle lenses. The 28-75mm F2.8 G2 achieves a MOD of 0.18m (7.1 in) at the wide-end, 1cm (0.4 in) closer than the Model A036, with a maximum magnification ratio of 1:2.7. This allows users to get even closer to the subject for wide macro photography, enabling powerful visual impact with the subject large while keeping a comprehensive view of the background in the frame.

Scratch and fingerprint-resistant, plus improved operability and texture.
The all-new 28-75mm F2.8 G2 features a new design. Certain internal parts of the zoom ring and focus ring have been enhanced, resulting in smoother overall operability. The perimeter of the lens barrel has been slimmed down to give the lens a contoured profile that makes it easier to grip. This creates a comfortable shape that fits snugly and naturally in the hand. Plus, the surface of the lens exterior is shiny black, much glossier than previous models. Improved abrasion resistance makes the lens barrel harder to scratch and more resistant to fingerprints. Look at the design differences between the Model A036 and the Model A063 G2.

Twice as fast: uses high-speed, high-precision VXD linear motor focus mechanism.
The AF drive system is equipped with a VXD linear motor focus mechanism. The AF speed is approximately twice as fast as the 1st-generation Model A036. With reliable, speedy focusing from the MOD to infinity and excellent focus tracking, you are ready for those crucial moments even when photographing fast-moving subjects.
