The Leica X-Ray is a specialised 35mm Leitz camera built for medical and scientific X-ray photography rather than general use. It belongs to a small group of purpose-built Leitz instruments produced in limited numbers, and survives today largely as a collector's item.

Auction evidence for the Leica X-Ray is extremely thin: a single Christie's hammer result from 2003 sold for £998, which is wholesale-level (commission excluded) and not directly comparable to today's retail asking prices. With only one data point on file as of 2026, any current value or price estimate must be treated as indicative, and what a Leica X-Ray sells for today will depend heavily on completeness, condition and the presence of original documentation.
