The lens will have a new optical construction and will use the company's VXD (Voice-coil eXtreme-torque Drive) linear focus motor technology, which we've found enables very swift focus speeds in Tamron's recent lens offerings. The minimum focus distance has dropped slightly to 18cm (7.1"), with the max magnification rising to 0.37x. The lens will also have refined ergonomics with focus and zoom rings that are well demarcated from the lens barrel thanks to their slightly greater diameter. Importantly, the new lens will remain just as compact as its predecessor.

By using the Tamron Lens Utility and optional connector cable, users will be able to change the function of the Focus Set button and focus ring. The Focus Set button can be programmed to switch between two pre-set focus positions or jump to one predefined position, or to any custom function assignable to the camera's custom buttons. The focus ring can be switched to operate as an aperture ring, and in manual focus mode its rotation direction and mode of operation (linear vs. non-linear) can be customized.

Pricing and availability were not disclosed.

TAMRON Announces Development of Second-generation Fast-Aperture Standard Zoom Lens for Sony Full-Frame Mirrorless Cameras

New 28-75mm F2.8 G2 offers significantly improved optical and autofocus performance and new function customization

August 4, 2021, Commack, NY - Tamron announces the development of a second generation fast-aperture standard zoom lens for Sony E-mount full-frame mirrorless cameras: 28-75mm F/2.8 Di III VXD G2 (Model A063). The lens is expected to launch in 2021.

Overview of the 28-75mm F/2.8 Di III VXD G2 (Model A063) features

The 28-75mm F2.8 G2 is the successor of the 28-75mm F/2.8 Di III RXD (Model A036), a popular zoom lens that has earned high evaluation worldwide. It reflects the fruits of continuous evolution and customer-focused refinement. Retaining the well-received compact size of its predecessor, the new 28-75mm F2.8 G2 incorporates a new optical construction based on a design that has been revamped to enhance imaging performance and its features are compatible with the latest model digital cameras that offer increased resolution. The AF drive, TAMRON’s VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism, is adopted to deliver higher autofocus speed with greater precision. With the MOD (Minimum Object Distance) of 7.1” at the wide end and a maximum magnification ratio of 1:2.7, the lens boasts advanced close-up shooting performance. Additionally, it features a new design in the pursuit of enhanced operability and ergonomic texture. TAMRON pioneered the category of compact fast-aperture standard zoom lenses for mirrorless cameras and the new 28-75mm F2.8 G2 truly is a next-generation lens for everyday use.

Originally developed software ‘TAMRON Lens Utility’ for lens function customization

This lens is compatible with the new ‘TAMRON Lens Utility’ software originally and uniquely developed by TAMRON. TAMRON Lens Utility can be operated via your computer by connecting the lens from its Connector Port via the optional TAMRON Connection Cable . Users can customize the functions and update the firmware through the lens rather than through the camera. The personal customization gives flexible shooting options to match the shooting situation such as still photography or videography.
