70-180mm F/2.8 Di III VXD
The 70-180mm F/2.8 features a compact and lightweight design with a 67mm filter diameter, the same as Tamron's highly esteemed 17-28mm F/2.8 (Model A046) and the 28-75mm F/2.8 (Model A036). The optical construction includes several special lens elements that contribute to the lens's overall superb imaging performance. Its very short 33.5" MOD (Minimum Object Distance) expands overall versatility. The lens utilizes Tamron's newly developed VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism that produces an autofocus drive that's quieter and quicker than ever before.
Additionally, a floating system is used to achieve excellent optical performance at all shooting distances. By simultaneously operating two VXD units via electronic control, the system produces clear and sharp images of all objects near and far. Other features that support a great shooting experience include Moisture-Resistant Construction for added weather protection and Fluorine Coating for easy maintenance. In addition, the 70-180mm F/2.8 is fully compatible with various camera-specific features including Fast Hybrid AF and Eye AF. Developed under the concept of "making large aperture zoom lenses user-friendly," the 70-180mm F/2.8 provides users with complete portrait-to-telephoto lens range coverage. This new model joins the 17-28mm F/2.8 Di III RXD and the 28-75mm F/2.8 Di III RXD to complete Tamron's fast zoom lens trinity for full-frame mirrorless cameras.
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 camera-based image stabilization.
It is small: filter diameter 67mm, maximum diameter 81mm, length 5.9" at the 70mm setting, and also light weight: 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"), 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 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-ed
