Originally posted by titrisol Well, since Electro Spotmatic = ES I think the ones from Pentax-Manuals.com are your best bet
If you mean the ES operates the same as the Electro Spotmatic, so the ES manual should be good enough that's good advice. If the OP specifically wants the Electro Spotmatic manual it is probably distinct.
The Electro Spotmatic actually is a distinct camera. The Electro Spotmatic was only offered in Japan Home Market. It actually has the full description engraved on the top plate. The electronics didn't work well and it was replaced in Japan by the ES, which was released globally.
From Asahi Optical Historical Club:
- Electro Spotmatic - Japan only - 1971-1972
- ES - Japan, Int'l, USA - 1971-1973
- ESII - Japan, Int'l, USA - 1973-1975
