Sleek and ultra-wide describe the 20mm f/2.8 Di III OSD M 1:2 Lens from Tokina; 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 everyday, walkaround shooting. Also contributing to its versatility is a half life-size 1:2 maximum magnification ratio and 4.3" minimum focusing distance for working with close-up subjects. 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.
