Tamron 20mm f/2.8 Di III OSD Lens for Sony FE

Designed specifically for mirrorless cameras, the Tamron 20mm f/2.8 Di III OSD is a must-have ultra-wide-angle lens for any photographer. The AF drive uses newly developed OSD technology for quiet, smooth operation, and four optical lens elements minimize chromatic aberrations and spherical distortion. Maximizing the perspective unique to ultra-wide-angle lenses, the Tamron 20mm delivers outstanding image quality from edge-to-edge, capturing amazingly sharp detail and rich texture.

Up for adventure

An extremely portable, ultra-wide-angle lens, the Tamron 20mm f/2.8 Di III OSD is just 2.5 inches (64mm) long and weighs less than half a pound (220g), so really can go anywhere. The overall length of the lens doesnt change when focusing, so extreme close-ups are possible without fear of accidentally bumping the front element. It shares the same 67mm filter diameter as many of the other Tamron lenses for Sony E-mount cameras, so polarizers and lens caps can also easily be shared.

Fast, quiet autofocus

The newly developed Optimized Silent Drive (OSD) in the Tamron 20mm f/2.8 Di III has been optimized to ensure precision and quiet tracking of constantly moving subjects. Operating noise has been significantly reduced, so its easy to shoot video without picking up any ambient drive sounds.

Sharp, bright images

Three Low Dispersion (LD) elements in the Tamron 20mm f/2.8 Di IIIOSD help minimize chromatic aberrations and color fringing, improving color accuracy. Spherical aberrations and other distortions are reduced with the molded glass aspherical element, generating sharp, accurate imagery. Lens surfaces are treated with Tamrons proprietary Broad-Band Anti-Reflection (BBAR) coating, helping to preserve a crisp image quality while reducing ghosting and flaring.

Get even closer

Boasting a Minimum Object Distance (MOD) of 4.3 inches and a magnification ratio of 1:2, the Tamron 20mm f/2.8 Di III OSD lens maximizes the dramatic perspective that is unique to ultra-wide-angle lenses. Produce stunning, unique images with beautifully blurred background bokeh.
