Genealogy

 Both of these cameras have a common ancestor, the German Zeiss Ikon Contax.  That fact turned out to be useful when the film advance on my recently acquired Nikon S locked up.

 

 

Since the Nikon S and the Kiev IIa both have Contax lens mounts, I was able switch lenses, putting the Nikkor-S 1.4/50mm on the Soviet-era Kiev IIa. As a test of the compatibility I loaded the Kiev with some expired Plus-X and took it to Old Town.
 

The Plus-X was from 2011 and had been in my refrigerator for about five years.  I thought at first that I would give it an extra stop of exposure to compensate for the film's age.  However, Bob Eggers told me he had better luck just shooting old Plus-X at box speed and developing longer than fresh film would require.  So I took his advice and processed in HC-110b for seven minutes at 20 °C.
