The 20mm f/2.8 Di III OSD M 1:2 Lens from Tamron; a flexible wide-angle prime designed for full-frame Sony E-mount mirrorless cameras. This lens uses a modestly bright maximum aperture to achieve a svelte and lightweight profile that is ideal for every day, walkaround shooting. An OSD stepping motor achieves fast and near-silent autofocus performance along with full-time manual focus override. Additionally, the lens sports a moisture-resistant physical design along with a fluorine coating to suit working in inclement conditions. Modestly bright f/2.8 maximum aperture strikes a balance between being suitable for working in available lighting conditions and realizing an impressively compact and lightweight profile. One molded glass aspherical element suppresses distortion and spherical aberrations for greater sharpness and more accurate rendering. OSD stepping motor offers especially quiet, fast, and precise autofocus performance along with full-time manual focus override.
