Tamron designed this compact and light-weight lens to be the ideal combination with a full-frame mirrorless camera. To achieve this diminutive size while maintaining the high performance of the F/2.8 aperture, Tamron selected the focal length of 180mm at the telephoto end and employed an innovative zoom mechanism. Also, the image stabilization features of the host camera body are utilized for shake-free shooting. The result is a compact telephoto zoom lens that is comfortable and easy to shoot handheld. Additionally, the filter diameter is the same 67mm as Tamron’s the other lenses for full-frame mirrorless cameras in the series. This feature makes filter-related tasks simple and removes the hassle of looking for front caps with differing diameters when changing lenses. The impressive portability of this lens expands its usefulness to many different fields of photography.
In developing the 70-180mm F/2.8, Tamron sought to strike a balance between compact size and light weight without sacrificing high image quality. The optical construction features 19 elements in 14 groups. The generous arrangement of special lens elements including XLD (eXtra Low Dispersion), LD (Low Dispersion), GM (Glass Molded Aspherical) and hybrid aspherical lens elements achieves exceptionally high resolving power and controls aberrations from image center to the edges. The BBAR-G2 (Broad-Band Anti-Reflection Generation 2) Coating is used to suppress ghosting and flare and to render subjects in exacting, full-contrast detail even under backlit conditions. In short, the lens delivers outstanding sharpness and enables clear expression, capturing the mood of any scene without compromise across the entire zoom range.
The MOD of the 70-180mm F/2.8 is just 0.85m (33.5 in) across the entire zoom range, a surprising accomplishment for a large-aperture telephoto zoom lens. Thanks to this short distance, at the 180mm telephoto end in particular, the Maximum Magnification Ratio is 1:4.6, allowing you to create powerful images. Moreover, a floating component equipped with two VXD linear motor 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. Users can experience unique photographic expressions and high image quality possible only with this lens.
A unique capability of the 70-180mm F/2.8 is shooting in the close-up range down to 0.27m (10.6 in) at the 70mm wide-angle end in manual focus (MF). While this mode makes it difficult to focus around the image periphery, it allows you to peer into a new world that can only be rendered by this lens. Discover this entirely new shooting experience.
