The Alpa 10s is a Swiss-made 35mm single lens reflex camera produced by Pignons SA of Ballaigues. It sits within the long-running Alpa reflex line that positioned the brand at the precision-engineered, low-volume end of the SLR market.

Sales data for the Alpa 10s is extremely thin: the only UK auction hammer record on file is a single result of £1,979 from 2004, so a reliable current price band cannot be drawn from this evidence alone. As of 2026, what an Alpa 10s is worth at saleroom level today depends heavily on cosmetic condition, mechanical health and whether a desirable Kern or Schneider lens is included, and a single historic hammer should not be read as a present-day median.
