The Leitz Leicina Prototype is a pre-production cine camera from Leitz's Leicina 8mm movie camera line. As a non-production prototype, it falls outside the standard catalogued Leicina range and would have been built as an internal development sample rather than a retail product.

Sales data for the Leicina Prototype is extremely thin: a single UK auction hammer result of £12,000 is on record (December 2010), which sets the only reference point for what the camera sells for at saleroom level. With just one data point, today's value is best treated as indicative rather than a true market median, and prototype-specific factors — provenance, documentation, and Leitz factory paperwork — will drive any future price far more than condition alone.
