Fast-handling telephoto zoom lens with a fast F/2.8 aperture
For full-frame mirrorless Sony cameras; light weight and responsiveness make telephoto shooting better than ever
The Tamron 70-180mm F/2.8 Di III VXD (Model A056) is a large-aperture telephoto zoom lens for Sony E-mount full-frame mirrorless cameras. The greatest feature is its outstanding performance even while attaining a fast F/2.8 aperture across the entire zoom range and offering the world’s lightest and most compact package with a filter diameter of 67mm, maximum diameter of 81mm, 149mm (5.9 in) length (at the 70mm setting) and a weight of 810g (28.6 oz). Thanks to the generous use of special lens elements, the 70-180mm F/2.8 achieves excellent image quality, and with the short MOD (Minimum Object Distance) of 0.85m (33.5 in), it also broadens the possibilities for photographic expression. For enhanced AF drive efficiency, Tamron has newly developed the VXD (Voice-coil eXtreme-torque Drive), a linear motor focus mechanism that delivers excellent quietness and agile performance, thereby producing the highest level of autofocusing speed and precision in Tamron’s history. 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. Moisture-Resistant Construction and Fluorine Coating are employed to facilitate outdoor shooting, and the lens is fully compatible with camera-specific features like Fast Hybrid AF. This remarkable 70-180mm F/2.8 is the third member of Tamron’s exciting trio of fast F/2.8 zoom lenses for full-frame mirrorless cameras.

*At the 70mm setting, it's possible to shoot at the close range of 0.27m when manual focus (MF) is set on the camera. However, results may be less than optimum since image quality decreases in peripheral areas. For more details, please visit this website: https://www.tamron.jp/en/support/guide/closeup.html
** Length is the distance from the front tip of the lens to the lens mount face.
*** The circular diaphragm stays almost perfectly circular up to two stops down from maximum aperture.

MTF (Modulation Transfer Function) curves describe to what extent the tested lens can faithfully reproduce contrast of the subject in images it captures.
The closer the 10 lp/mm (line pairs per millimeter) curve (the thick line for low frequency) in an MTF chart to "1" of the vertical axis (the higher up), the higher the contrast reproduction performance of the tested lens will be. The closer the 30 lp/mm curve (the thin line for high frequency) to "1" (the higher up), the higher the resolving power and thus the subjective sharpness of the lens will be.
Lens performance differs depending upon directions. Solid lines show performance in the sagittal (radial) direction while dotted lines indicate performance in the meridional (circumferential) direction. When sharp lenses capable of delivering uniform optical performance over the entire image field are tested, MTF charts show curves plotted in good balance.
Performance characteristics of photographic lenses cannot be expressed with only MTF charts. There are other factors that are expressed in different methods, such as taste of softness and degrees of compensation of various aberrations. But you can use MTF charts as a scale to measure lens performance.
