June 11, 2020, Saitama, Japan – Tamron Co., Ltd. (President & CEO: Shiro Ajisaka), a leading manufacturer of optics for diverse applications, announces the launch of the 28-200mm F/2.8-5.6 Di III RXD (Model A071), an all-in-one zoom lens for Sony E-mount full-frame mirrorless cameras on June 25, 2020. However, due to the spread of COVID-19, the release date or the product supply schedule could be delayed.
In 1992, Tamron demonstrated breakthrough innovation with the release of the AF 28-200mm F/3.8-5.6 Aspherical (Model 71D), a compact and lightweight all-in-one zoom lens. The amazingly compact size, light weight and reasonable price immediately became wildly popular with photographers around the world. In the years since, Tamron has been a pioneer in releasing epoch-making all-in-one zooms tailored to each era, including the recent 18-400mm F/3.5-6.3 Di II VC HLD (Model B028) that boasts the world’s highest*2 magnification of 22.2x and which currently enjoys robust sales. The new 28-200mm F2.8-5.6 is a distillation of all Tamron’s accumulated all-in-one zoom expertise, and has been specifically developed as an all-in-one zoom for daily use on a full-frame mirrorless camera. Tamron chose Model A071 as the model name in a nod to “71” representing the world’s original all-in-one zoom.
The 28-200mm F2.8-5.6 is the first all-in-one-zoom in the world to achieve a maximum aperture of F2.8 at the 28mm wide-angle end. To assure superb optical performance, it features a precise arrangement of special lens elements that accommodate the increasingly high resolutions of today’s digital cameras. Enabling high quality image rendering throughout the zoom range, the lens responds to users’ photographic expressions in powerful style. Moreover, with its 117mm (4.6 in) length, 575g (20.3 oz) weight and filter diameter of a mere 67mm, the 28-200mm F2.8-5.6 offers excellent portability. When combined with a compact, lightweight full-frame mirrorless camera, it allows photographers to capture virtually every scene they encounter in daily use, travel, sports and nature.
The 28-200mm F2.8-5.6 takes the convenience of an all-in-one zoom (which incorporates various angles of view from wide to telephoto in a single lens) and adds a fast-maximum aperture of F2.8 and superb image quality to enhance the potential for photographic applications. Breaking conventional limitations and broadening the horizons of photographic possibilities, this zoom lens writes a new chapter in the history of the all-in-one zoom lens.
