Sony 20mm F/2.8 Alpha Mount Autofocus Lens {72} Description


The Sony 20mm f/2.8: compact lens, with the body about as small as the Minolta 28mm f/2.8, and a front element the size of the Minolta 28-70 f/2.8 G. The Sony 20mm f/2.8 was designed in the mid 1980s by Minolta, but re-styled in early 1990. The 20mm focal length is equivalent to 30mm focal length which places it in the wide-angle lens category with various applications. The lens features seven-bladed circular aperture and an efficient manual focusing ring. The lens has a multi-coated finish to prevent flare and ghosting.
