The Tamron 20mm f2.8 Di III OSD M 1:2 Lens is a compact, ultra-wide prime for Sony E-mount full-frame and APS-C cameras. Clocking in at just 221 g, it offers a bright f/2.8 aperture with a unique 1:2 macro capability thanks to its 11 cm minimum focusing distance—ideal for dramatic, close-up compositions. Its optical design includes three LD and one GM aspherical element with BBAR coating, delivering sharp, low-distortion images across the frame. The OSD stepping motor provides quiet and reasonably quick autofocus with full-time manual override. Weather-sealed and featuring a fluorine-coated front element, it's rugged and travel-ready. While barrel distortion requires correction, this lens offers excellent image quality and creative versatility in a pocket-sized package.
