Konica S II
The Konica S II was first offered in 1961 as a modest update of the S. It utilizes a Copal SVE shutter and is only found in one version with Hexanon 48mm f2 lens. (Note the front barrel of the lens is black finished on this model, on the earlier model it was chromed). There is also a small window added right above the meter cell housing on the front of the camera. Presumably this is to admit additional ambient light within the camera's viewfinder, probably to illuminate the meter scale which is now visible.
Like the earlier and later S models (not to be confused with the Auto S models), the meter often fails or is inaccurate, due to degradation of the selenium cell sensor. This doesn't effect the usability of the camera, it just means using a separate handheld meter or setting exposure by eye.
