Asahi Pentax S1a

{"overview":"The Asahi Pentax S1a is a 35mm single-lens reflex camera made by Asahi Optical Co. as part of the Pentax S-series of M42 screw-mount bodies from the 1960s. These are wholesale auction results rather than dealer retail, and condition — not rarity — is the main driver, with clean, working bodies selling for noticeably more than scruffy ones. Expect a private or dealer asking price above these figures once commission, warranty and handling are factored in.","buying_guide":"Common faults on M42-era Pentax bodies include sticky slow shutter speeds, hardened light seals around the film-back door, deteriorated mirror-damper foam, and dim or separated pentaprism silvering, so fire the shutter at every speed and check the viewfinder carefully.
