Compact size maximizes the mobility advantages of mirrorless cameras
A true marvel of portability and utility, the 70-180mm F/2.8 incorporates an innovative zoom mechanism and 180mm telephoto power. It was possible to maintain extreme light weight and compactness even while attaining a fast F/2.8 aperture across the entire zoom range by leveraging the camera-based image stabilization. It is small: filter diameter 67mm, maximum diameter 81mm, length 149mm (5.9 in) at the 70mm setting, and also light weight: 810g (28.6 oz). The super-compact size helps make handheld shooting a breeze. As part of our constant, ongoing effort to achieve both high image quality and supreme compactness, Tamron went to great lengths to create this product in answer to demands of the new generation of digital cameras.
Newly developed VXD linear motor focus mechanism delivers high-speed and high-precision autofocus performance
Tamron developed its first-ever linear motor AF drive focus mechanism, VXD (Voice-coil eXtreme-torque Drive), especially for the 70-180mm F/2.8. While operating faster than ever before, the drive also maintains positional accuracy down to 0.005mm (0.0002 in), less than one tenth the width of a human hair! This provides unprecedented fast and precise AF performance. A floating system that uses two high-speed, high-precision VXD units with advanced electronic control is also used. This innovative design produces clear and beautiful images of all objects form near to far and at the same time helps reduce size and weight. In addition, its exceptional quietness enables low-noise shooting in silent settings. Active athletes and moving vehicles are among the subjects commonly photographed with telephoto zoom lenses. The enhanced, highly-responsive focus features of the 70-180mm F/2.8 enable following a subject’s movements to provide users with a whisper-quiet, high-precision shooting experience, not just for still images but also video.
Superior design for uncompromised image quality
The 70-180mm F/2.8 has an optical construction of 19 elements in 14 groups. It includes a total of six XLD (eXtra Low Dispersion) and LD (Low Dispersion) lens elements combined, and three GM (Glass Molded Aspherical) and hybrid aspherical lens elements combined. Special lens elements are generously and optimally arranged to correct chromatic aberration and maintain very high-resolution performance from edge-to-edge. This model also features BBAR-G2 (Broad-Band Anti-Reflection Generation 2) Coating, which minimizes ghosting and flare and produces stunning, clear images with brilliant, sharp subject detail. Furthermore, excellent high image quality across the entire zoom range is enhanced by camera-based distortion and shading correction. Additionally, the bokeh effect obtained using the fast F/2.8 aperture delivers beautifully smooth and soft transition from the subject to the background. The images created with this lens are emblematic of Tamron’s pursuit to combine supreme compactness with superb image quality.
67mm filter diameter for system convenience
The 70-180mm F/2.8 features the same 67mm filter diameter as Tamron’s other lenses for full-frame mirrorless cameras including the 17-28mm F/2.8 (Model A046), an ultra wide-angle zoom, and the 28-75mm F/2.8 (Model A036), a standard zoom, as well as the fixed focal lens series (20mm, 24mm and 35mm). This uniformity significantly reduces cost and trouble when working with PL, ND and other filters. Even the front lens caps are the same size, eliminating the hassle of sorting caps when switching lenses. These features combine to produce a highly convenient and mobile system that adds more fun to photography.
Close focusing to a mere 0.85m (33.5 in)
The new 70-180mm F/2.8 lens has a MOD of 0.85m throughout the entire zoom range. This is astonishingly close for a large aperture telephoto zoom lens. The short MOD paves the way for impressive telephoto shooting at a maximum magnification ratio of 1:4.6 at the 180mm telephoto end. Moreover, a floating component equipped with two VXD linear focus mechanisms maintains high image quality while effectively controlling aberrations so that the 70-180mm F/2.8 ensures great image quality even at close-up. To effectively suppress optical aberrations, this lens features a floating mechanism that ensures great image quality at distances as short as 0.85m (33.5 in).
Moisture-Resistant Construction, Fluorine Coating, and Zoom Lock switch
Seals are located at the lens mount area and other critical locations to deter infiltration of moisture and/or rain drops and afford Moisture-Resistant Construction. This feature provides an additional layer of protection when shooting outdoors under adverse weather conditions. Also, the front surface of the lens element is coated with a protective fluorine compound that has excellent water- and oil-repellant qualities. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, moisture or oily fingerprints, allowing for much easier maintenance. Additionally, the conventional Zoom Lock switch prevents unwanted barrel extension during transportation.
Tamron’s ‘Dream Team’ of large aperture zooms for full-size mirrorless cameras
Tamron’s 17-28mm F/2.8 Di III RXD (Model A046) ultra wide-angle zoom and the 28-75mm F/2.8 Di III RXD (Model A036) standard zoom lens earn high marks for user-friendliness and high image quality among large aperture zoom lenses for the Sony E-mount. Now, the 70-180mm F/2.8 Di III VXD (Model A056) telephoto zoom lens joins the lineup to complete the Dream Team of high-speed zoom lenses for full-size mirrorless cameras. A key advantage of this series is their portability. The three models altogether weigh surprisingly little, just 1,780g (62.8 oz). Featuring light weight, compact size, a fast F/2.8 aperture and superb image quality, Tamron’s Dream Team is easy to carry, easy to deploy and easy to enjoy.
