The Konica Hexanon AR1.7/57 mm is an early fast normal lens. It did replace the Hexanon 1.4/52mm for the F bayonet which had been produced in quite low quantities for the Konica F and the Konica FM/FS/FP series. The AR 1.4/57 mm has six lenses in five groups and resembles the Minolta 1.4/58 mm (which in fact was an 1.4/60 mm). Nikon had a 1.4/58m Nikkor as well, but it did consist of seven lenses and was replaced quite soon by the classical 1.4/50mm Nikkor.

Both the Hexanon 1.4/57 mm as well as the Rokkor 1.4/58mm (especially in its later MC-II incarnation) perform pretty well. Of course, the image is very soft wide open, but stopping down to f5.6 or f8 results in sharp images with a well balanced contrast. Both these lenses are suitable for shooting "vintage" portraits (either wide open or af f2, preferably black and white of course), and both can be used for landscape photography if stopped down to f5.6 or f8. On 24 MP full frame cameras, the Hexanon is perfectly sharp even in the extreme corners when stopped down to f8; no lateral CAs are visible.
