Flexible zoom range, fast design, and compact profile, the Tamron 70-180mm f/2.8 Di III VXD is a unique take on the ubiquitous and popular telephoto zoom. Designed for full-frame Sony E-mount cameras, this lens spans a useful short-telephoto to mid-telephoto range and is characterized by its f/2.8 maximum aperture to suit working in available light conditions and for controlling depth of field. A sophisticated optical design includes a series of low dispersion and aspherical elements to correct a variety of aberrations and a BBAR-G2 coating helps to reduce flare and ghosting for high contrast and color accuracy. Additionally, a floating elements system is used to ensure consistent image quality throughout the focusing range, from 2.8' to infinity. Autofocus is handled by a pair of VXD linear motor units, which deliver notably fast, accurate, and quiet focusing performance, and full-time manual focus control is also available. Suiting this lens's use in inclement weather conditions, it also features a moisture-resistant construction along with a fluorine-coated front element to protect against fingerprints and smudging.
