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 the 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. 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. Bright constant f/2.8 maximum aperture affords consistent brightness throughout the zoom range and offers improved control over depth of field. Three aspherical elements, including both glass-molded and hybrid types, help to reduce spherical aberrations and distortion for high sharpness and accurate rendering throughout the zoom range.
