The Tamron 28-200mm F2.8-5.6 is the world's first all-in-one-zoom to achieve a maximum aperture of F2.8 at the 28mm wide-angle end. The new lens takes the convenience of an all-in-one zoom and adds a fast-maximum aperture of F2.8 and remarkable image quality to enhance the potential for photographic applications. 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. With its 4.6" length, 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. 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.
Unprecedented blend of optical performance and versatility New, innovative all-in-one lens that does it all Tamron has distilled all the technical capabilities and know-how amassed over the last 28 years in its development of all-in-one zoom lenses into the creation of this 28-200mm F/2.8-5.6 Di III RXD (Model A071), designed exclusively for Sony E-mount. The lens has a large maximum aperture of F2.8 at 28mm wide end, which represents a world’s first* for all-in-one zoom lenses, and delivers high-level performance across the entire zoom range, from the 28mm wide-angle end to 200mm telephoto. Despite covering a wide range of focal lengths, the lens is lightweight and compact, with a length of 117mm (4.6 in) and a weight of 575g (20.3 oz). Aside from day-to-day portability, the 28-200mm F2.8-5.6’s lightweight and compact size make it especially convenient for travel photos, where users wish to avoid the burden of heavy baggage. Tamron has also taken an uncompromising approach to optical performance, making liberal use of special lens elements—including LD (Low Dispersion) and XLD (eXtra Low Dispersion) —to greatly suppress chromatic aberrations, and making it possible to achieve high image quality from edge to edge. With an 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. When it comes to all-in-one zooms, the innovative 28-200mm F2.8-5.6 is in a class by itself and vividly captures virtually all possible scenes, from landscape photography to portrait photos and snapshots.
A new model “71” that reinvents the notion of all-in-one zoom lenses In 1992, Tamron launched its first all-in-one zoom lens, the AF 28-200mm F/3.8-5.6 Aspherical (Model 71D). At that time, the Model 71D astonished the world and overturned the existing perception of all-in-one zoom lenses as being large, heavy and delivering poor image quality. Since then, Tamron has continued to develop and innovate as a pioneer in the field of all-in-one zoom lenses, delivering a stream of ground-breaking models such as the 18-400mm F/3.5-6.3 Di II VC HLD (Model B028), delivering the world’s only 22.2x zoom ratio. Now the Model A071, too, shares the legendary name “71” given to Tamron’s revolutionary all-in-one zoom lens: a name infused with the destiny to write a new chapter in the history of all-in-one zoom lenses.
Compact, lightweight design offering superior portability with all-in-one zoom versatility From wide-angle to telephoto, all-in-one zoom lenses deliver a wider range of usefulness, from everyday snaps to travel and much more. That’s why Tamron pursued a high level of portability in the development of the 28-200mm F2.8-5.6, achieving a compact, lightweight design that’s a mere 117mm (4.6 in) long and weighs just 575g (20.3 oz). The small size enables comfort and convenience, even during extensive travel, without the burden of a heavy camera bag. The 67mm filter size is the same as other lenses in Tamron’s mirrorless lens lineup*. This means that the filters such as PL (Polarizer) and lens caps can be used for all models in the series, for greater convenience and less hassle during lens changes.
Maximum aperture at the 28mm setting is a blazing fast F2.8 The 28-200mm F2.8-5.6 is the first all-in-one zoom lens for full-frame mirrorless cameras to offer a maximum aperture of F2.8. It maintains outstanding performance throughout the entire zoom range, and aperture values of F3.5 at 50mm, F4.5 at 100mm, F5.6 at 200mm. From landscape photography to portrait photos and snapshots, the 28-200mm F2.8-5.6 delivers finely detailed images in a wide range of shooting situations. The generous use of special LD and XLD lens elements (with properties close to those of fluorite) enables it to thoroughly minimize chromatic and other aberrations, while the application of BBAR (Broad-Band Anti-Reflection) Coating offers high anti-reflective benefits and reduces ghosting and flare that are otherwise likely to occur when shooting backlight scenes. Additionally, by leveraging camera functionality, the lens delivers excellent optical performance to match the high-resolution image sensors on the latest cameras, achieving beautiful images that are a cut above all-in-one zoom lenses of the past.
Close-up shooting performance that’s astonishing for an all-in-one zoom lens The 28-200mm F2.8-5.6 delivers amazing close-up performance for an all-in-one zoom lens. At 28mm wide-angle, the MOD is 0.19m (7.5 in) with a maximum magnification ratio of 1:3.1, and at the 200mm telephoto end it has an MOD of 0.8m (31.5 in) with a maximum magnification ratio of 1:3.8. In addition to capturing stunning close-up images, you can leverage the blurred background bokeh utilizing a large F-number and enjoy unique close-up shots that were not possible with all-in-one zoom lenses until now.
