I’ve collected scattered coverage into a formal review of the Olympus Zuiko Auto-S 50mm f/1.2, and added a modern evaluation on the Sony A7R, using my copy that I had converted to Nikon F-mount some years ago.
Can a 30+ year old lens design deliver high-speed satisfaction on modern digital?
I like manual focus and manual aperture control on both DSLR and mirrorless. Moreover an f/1.2 lens always has a certain appeal, so how does the Zuiko 50/1.2 deliver over its aperture range?
Of particular interest is the bokeh of such designs, and here the Zuiko 50/1.2 is surely a winner even as it impresses with sharpness too (but expectations for contrast at f/1.2 should not be set too high).
