The Tamron 28-75mm F/2.8 Di III VXD G2 (Model A063) provides outstanding resolution and superb overall performance in a lightweight and compact zoom lens for Sony E-mount full-frame mirrorless cameras. High definition and spectacular image quality are the key areas of advancements. The Model A063 features a redesigned optical system but maintains a size similar to its predecessor. The lens provides exceptionally strong optical performance, edge-to-edge across the frame, throughout the entire zoom range, along with the soft, beautiful bokeh effects that are distinctive to fast aperture lenses. The lens features Tamron’s VXD autofocus motor to enable high speed, high precision auto-focusing. Closeup shooting capabilities have also been improved and achieve an MOD of 7.1” at 28mm and a maximum image magnification ratio of 1:2.7. It is equipped with new, groundbreaking features that enable users to easily perform customization and firmware updates themselves. For example, users can reverse the direction of the focus ring for manual focus operation. Additionally, Tamron has adopted a new design with improved ergonomics and revised the exterior coating of the lens body to improve scratch resistance. The filter size is 67mm, which is standard among Tamron's fast aperture zoom lens series and enables the sharing of lens caps, filters, and other accessories. In addition to features such as Moisture-Resistant Construction and a protective Fluorine Coating, the lens supports various features built into Sony E-Mount cameras, including Fast Hybrid AF, Eye AF and in-camera lens corrections (shading, chromatic aberration, distortion).

The optical design of the Sigma AF 28-70mm f/2.8 DG DN is based on the 24-70mm F2.8 DG DN | Art, which is renowned for its outstanding optical performance throughout its zoom range. True to the Contemporary line's core concept, the 28-70mm F2.8 DG DN | Contemporary was developed to offer the right balance of performance and portability, and as such, this large-aperture standard zoom delivers outstanding image quality that rivals Art line lenses in a body light enough for day-to-day use. Building on state-of-the-art technology, the 28-70mm F2.8 DG DN | Contemporary has an advanced optical design that includes three aspherical, two FLD, and two SLD elements. In short, the Sigma 28-70mm F2.8 DG DN | Contemporary combines all of the key optical features required of a large-aperture standard zoom lens, which are essential for photographing a wide variety of subjects in a range of shooting conditions.

The Tamron 28-200mm F/2.8-5.6 (Model AFA071S-700) is the world’s first all-in-one zoom to achieve a maximum aperture of F2.8 at the 28mm wide-angle end. Despite covering a wide range of focal lengths, the lens is lightweight and compact, making it convenient to bring along for all your picture taking needs. When combined with a compact, lightweight full-frame/APS-C mirrorless camera, it allows photographers to capture virtually every scene they encounter in daily use, travel, sports and nature. Tamron did not compromise on optical performance. The use of special lens elements—including LD (Low Dispersion) and XLD (eXtra Low Dispersion)- help suppress chromatic aberrations, making it possible to achieve high image quality from edge to edge. With a MOD (Minimum Object Distance) of 0.19m (7.5 in) at the wide end and 0.8m (31.5 in) at the telephoto end, the lens also offers high-level close-up shooting performance. The AF drive system is powered by the RXD (Rapid eXtra-silent stepping Drive) stepping motor unit to deliver high-speed, high-precision performance. The lens also features Moisture-Resistant Construction and Fluorine Coating for added protection.
