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 characterised 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. This lens looks to be in near mint condition with almost no signs of use. The optics are clean and clear with no marks or scratches. The lens barrel shows almost no cosmetic marks. The focus ring is smooth and in great condition. The lens mount is in great condition showing almost no signs of use.
