Description
Tamron 70-180mm f2.8 Di III VXD (Sony E-Mount Fit) Lens
- Compact (149mm), comfortable and lightweight (815g)
- Next-generation VXD focus motor with extremely fast and quiet linear mechanism
- Compatible with Sony camera specific features including Fast Hybrid AF and Eye AF
- Special sealing and fluorine coating protects the lens to enjoy photography in any condition
- Optimal optical performance and a minimum focus of only 0.85 m for versatility
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 lightweight and compactness even while attaining a fast F/2.8 aperture across the entire zoom range by leveraging camera-based image stabilization. It is small: filter diameter 67mm, maximum diameter 81mm, length 149mm (5.9 in) at the 70mm setting, and also lightweight: 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 the demands of the new generation of digital cameras.
Newly developed VXD linear motor
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 from 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 for 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).
