Product Description
For full-frame mirrorless Sony cameras; light weight and responsiveness
make telephoto shooting better than ever.
The 70-180mm F/2.8 Di III VXD (Model A056) large aperture telephoto zoom
lens is designed for Sony E-mount full-frame mirrorless cameras and is just as
comfortable on APS-C mirrorless as well. The greatest feature is its superb
performance even while attaining a high-speed F/2.8 aperture across the entire
zoom range and offering the world's lightest and most compact package at just
5.9" length (at the 70mm setting) and a weight of 28.6 oz. Thanks to the
generous use of special lens elements, the 70-180mm F/2.8 achieves excellent
optical performance from center to edge. With the short MOD (Minimum Object
Distance) of 33.5", the 70-180mm F/2.8 expands the possibilities for
photographic expression. For the AF drive, Tamron has newly developed the VXD
(Voice-coil eXtreme-torque Drive), a linear motor focus mechanism that delivers
high-speed and high precision autofocus performance for both stills and video.
Add it all together and you can go light while going long-and get the shot!
The highest levels of autofocus speed and precision in Tamrons 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.
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 Tamrons 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.
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.
