## Long description

The Tamron 20mm F/2.8 Di III OSD M1:2 (Model F050) is an ultra-wide, fixed focal-length lens designed for Sony E-mount full-frame mirrorless cameras. Compact and lightweight at 220 g with a 64 mm length and 67 mm filter thread, it delivers wide-angle perspectives while allowing unusually close focusing down to 0.11 m (maximum magnification 1:2). Constructed with specialized glass elements (LD and GM) and Tamron’s BBAR coating plus a fluorine front coating, the lens offers controlled aberrations, reduced flare and reliable outdoor use with moisture-resistant construction.
Advantages
The lens combines ultra-wide coverage with a relatively fast F/2.8 aperture and a very short minimum object distance, enabling dramatic perspective and close-up compositions with pleasing background separation. Optical elements including LD and GM glass minimize chromatic and other aberrations across the frame, while BBAR coating reduces ghosting and flare. The OSD (Optimized Silent Drive) autofocus system provides quiet, accurate focusing. Its small size, light weight and consistent overall length during focusing make it highly portable and easy to handle in the field.
Suitable for
Landscape photography
Street and travel photography
Architecture and interior shots
Creative close-up wide-angle compositions

How to use
Attach the lens to a compatible Sony E-mount full-frame mirrorless camera and enable the camera’s lens correction functions if available for optimal image quality. To exploit the lens’s close-focusing capability, move physically close to your subject (down to 0.11 m) and compose so that foreground elements accentuate perspective. Use the F/2.8 aperture for low-light situations or to increase subject separation; stop down toward F/8–F/11 when maximum depth of field and edge-to-edge sharpness are required. The OSD autofocus provides quiet focusing; when precise focus is critical, use single-point AF or manual focus with focus peaking if available on the camera body.
Usage recommendations
For outdoor and architectural work, keep the fluorine-coated front element clean and use the 67 mm standard filters (polarizer, neutral density) to control reflections and exposure. When shooting close-up wide-angle compositions, pay attention to distortion of straight lines and use the camera’s lens correction or post-processing tools as needed to correct perspective and chromatic aberration.
