Minolta's ultra-wide for A-mount — the AF 20mm f/2.8 for wide-angle photography.
The Minolta AF 20mm f/2.8 is a wide-angle prime from Minolta's A-mount autofocus system for the Dynax/Maxxum SLR line, providing a classic wide-angle perspective with f/2.8 maximum aperture. It is directly compatible with Sony Alpha A-mount digital cameras for full autofocus operation.
The lens delivers 20mm at f/2.8 maximum aperture with Minolta A-mount autofocus coupling, full-frame coverage, and a field of view suited to architecture, landscape, interiors, and environmental portraiture. Standard Minolta consumer-professional build quality.
On Sony Alpha A-mount bodies, the 20mm f/2.8 delivers a versatile wide-angle perspective with Sony's in-body SteadyShot stabilisation applied, compensating for the lack of optical stabilisation in the lens itself. It is an affordable wide-angle option for Sony A-mount users building out a lens collection with vintage Minolta glass.
Check autofocus operation for speed and accuracy on a Sony Alpha body. Inspect aperture blades for oil contamination — common in older Minolta lenses — and verify blades close cleanly. Examine the front element for cleaning marks or coating damage. Confirm focus accuracy at architecture and landscape distances typical of wide-angle use.
