Konica Auto S2

Konica Auto S2 ad

This is the Konica Auto S2 produced by Konishiroku starting in 1965. It was also sold in the United States as the Wards am551. Along with a light meter, it has a fixed f1.8 45mm Hexanon lens and as the name implies, auto mode.

Regarding the light meter, the original battery was a PX625 mercury battery at 1.35v, which are no longer available. Knowing full well that the readings will not be entirely accurate this camera currently has a Duracell 625A (1.5v) installed. A more suitable option is the WeinCell MRB625 zinc-air battery.

This particular Copal-SVA shutter needed a bit of naphtha and exercise but is now working as smoothly as the day it left the factory.

  1. I have one of these and it’s really pleasant to use. I say bah to the whole worry about wrong voltage with the PX625. If you shoot print film the exposure latitude will make up for the voltage difference. I do it all the time and it’s fine.
