The 70-180mm F/2.8 Di III VXD telephoto zoom lens is the third in Tamron’s line-up of fast F2.8 zoom lenscreated for Sony E-mount full-frame mirrorless cameras

A floating system is used to achieve excellent optical performance at all shooting distances
In addition, a floating system is used to achieve excellent optical performance at all shooting distances. By simultaneously operating two VXD units viaelectronic control, the system produces impressive optical performance throughout the focus and zoomrange.
Construction of the 70-180mm VXD lens includes several special lens elements that contribute to itssuperb imaging performance. The very short 0.85m MOD (Minimum Object Distance) expands its overallversatility as well, making it great for close up’s too.
Its 67mm filter diameter is also common with other Tamron lenses for Sony E mount full frame cameras, adding to user convenience when having a range of Tamron lenses in this series.
