The Asahi Pentax SP500 is a 35mm single-lens reflex film camera from the Spotmatic family, produced in the late 1960s as a lower-cost variant of the Spotmatic line. It uses the M42 screw lens mount and was positioned as an entry-level body for buyers who wanted Pentax build quality without the top features of the standard Spotmatic.

Auction evidence for the SP500 is extremely thin: the only UK hammer result in our dataset is a single sale at £47 from 2003, so a reliable current price cannot be quoted. Today in 2026 the camera sells for modest sums at saleroom level when it does appear, but with one auction-hammer data point (wholesale, before commission) we cannot give a meaningful range or median for what the SP500 is worth.
