The Tamron 20mm F/2.8 Di III OSD M1:2 (Model F050) for Full-Frame Sony E-mount camera’s, is a great entry into the world of ultra-wide-angle photography. Developed under the concept of "introducing as many people as possible to the pleasure of shooting with fixed focal lengths", the Tamron 20mm F/2.8 ensures a balance between beautiful image reproduction and superior image sharpness. Despite the high image quality, Tamron managed to keep the filter size at the same 67mm as the other dedicated Tamron Sony FE lenses.
