The Nikon S is a 35mm rangefinder camera body from Nikon's early postwar rangefinder line. The "8 digits" designation refers to the eight-digit serial-number range used on later production examples, a detail collectors track when assessing originality.

Sales data for this specific serial range is thin: a single UK auction hammer result from November 2021 reached £434, which sets the only firm reference point for what the camera sells for at saleroom level. With just one wholesale data point on file, today's value is best treated as indicative rather than a reliable median, and condition, completeness and matching-number originality will move the price materially either way.
