The Tamron 12-20mm F2.8 (Model A084) is the first constant-aperture full-frame zoom to reach 12mm, delivering a dramatic 121°58' to 94°30' field of view for Sony E and Nikon Z mirrorless cameras. Despite its class-leading reach, it stays remarkably compact at 119.3mm and 570g (Sony E), with a 17-element, 12-group optical design, fast VXD autofocus, and a 12-blade circular diaphragm. A 0.18m minimum focus distance at the wide end enables striking close-up perspectives, while moisture-resistant construction, an integrated rear filter holder to compensate for the fixed petal hood, and TAMRON Lens Utility support for focus customisation and firmware updates round out the package.
Actual specifications may vary slightly depending on the specific lens mount version. Always consult the manufacturer's documentation for the most accurate data.
