Konica's Auto S2 — fixed-lens 35mm rangefinder, 45mm f/1.8 Hexanon, shutter-priority auto, 1965.
The Konica Auto S2, from 1965, was a fixed-lens 35mm rangefinder that updated the earlier Auto S. It was well regarded for its lens quality and became one of the better-known Konica rangefinders of the mid-1960s.
This is a 35mm coupled-rangefinder camera with a fixed 45mm f/1.8 Hexanon lens and a mechanical leaf shutter. Exposure is shutter-priority automatic using a built-in CdS meter, with a manual option, and the meter reads through a cell mounted around the lens. The shutter fires mechanically, while the meter and automation require a battery.
The Auto S2 suits general, street and travel photography, valued for the sharpness of its Hexanon lens and its bright rangefinder finder. It is a substantial metal-bodied camera with a comfortable finder and shutter-priority automation, at the cost of some weight.
On inspection, test the CdS meter and note that the original mercury cell is obsolete, so a modern substitute is generally required. Check the lens for haze and fungus, confirm the leaf shutter and aperture blades work cleanly, and verify rangefinder patch contrast and alignment. Replace perished light seals as needed.
