The Siemens & Halske C 'Marine' is a sub-cine motion-picture camera for 16mm film, produced for marine and field use. It sits within the Siemens C family of amateur and professional cine cameras from the mid-twentieth century.

Evidence on what this camera is worth in today's market is thin, with a single UK auction hammer result on file at £300 in 2018 — a wholesale saleroom level that excludes commission. With only one data point, the price a Siemens & Halske C 'Marine' sells for in 2026 should be treated as indicative rather than a reliable median, and condition and completeness of any 'Marine' accessories will move the value materially.
