Compact and light-weight body facilitates active telephoto shooting
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.
The highest levels of autofocus speed and precision in Tamron’s 70 year history
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. Focus tracking has been vastly improved to facilitate sports and racing photography, two common subjects for telephoto zooms. This ensures that those dramatic, action-packed moments are never missed, whether shooting still photos or video. Additionally, this zoom offers superior quietness, making it ideal for shooting in low-noise environments as the linear motor is structured to reduce the vibrations produced during drive operation (as compared to a conventional drive system).
Outstanding image quality to capture the ambience of the moment
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.
MOD (Minimum Object Distance) of just 0.85m (33.5 in)
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.
Close-up photography at 0.27m (10.6 in) to unleash a new shooting experience
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.
Moisture-Resistant Construction protects your lens
For greater protection when shooting outdoors, leak-resistant seals throughout the lens barrel help protect your equipment.
Fluorine Coating for protection and safe cleaning
The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints.
Circular Aperture to Produce a Smooth-Edged Bokeh
A 9-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening even when stopped down by two stops from the wide-open aperture. This produces a smooth-edged bokeh in background light spots.
BBAR-G2 Coating delivers stunning clarity and contrast
Tamron has long been an innovator of coating technologies that prevent ghosting and flare. Second-generation BBAR-G2 Coating is a groundbreaking advancement that provides vastly improved performance compared to the original BBAR (Broad-Band Anti-Reflection) Coating. The coating corrects for ghosting and flare to an unprecedented extent, and renders fine subject detail with true clarity and stunning contrast even under backlit conditions.
Tamron’s lineup of three large aperture zoom lenses for full-frame mirrorless cameras
With the addition of this telephoto zoom to the lineup of light-weight, high performance lenses, Tamron has completed its assortment of three F/2.8 large aperture zoom lenses for Sony E-mount full-frame mirrorless. The other two models are the 17-28mm F/2.8 Di III RXD (Model A046) ultra-wide zoom, and the 28-75mm F/2.8 Di III RXD (Model A036) standard zoom. The greatest feature of the series is the excellent portability. Combined, the three lenses are unbelievably light at just 1,780g (62.8 oz), fulfilling the photographer’s dream of being able to easily carry three fast, potent zoom lenses at the same time.
Pursue a wide range of photography with a lineup of lenses that all have the same 67mm filter diameter
Great things come in compact packages! This lineup includes other lenses that share the same filter diameter of 67mm. Lenses in this series feature small and light designs suitable for pairing with mirrorless cameras, and the filter diameter of each lens is the same 67mm. In addition to providing excellent portability when carrying multiple lenses, costly Polarizers, ND and other filters can be used interchangeably. Plus, the hassle of looking for different-sized lens caps when switching lenses has been eliminated. In addition to outstanding optical quality, you will enjoy the highest level of convenience across the entire lineup.
