The Leitz O-Series is a 35mm rangefinder-style camera offered in several variants, including reissues dated 1980, 2000 and 2004, available with either a tubular or flip-up viewfinder configuration. It sits in the collector segment of the Leitz catalogue rather than the working-photographer line.

Auction data for the O-Series is extremely thin: cameraworth.com has logged a single UK hammer result, £1,375 from November 2004, achieved at saleroom level (wholesale, before commission). With no recent comparable sales recorded, what a Leitz O-Series is worth today cannot be reliably triangulated from this dataset alone, and any current price quoted in 2026 should be treated as indicative only until further results come in.
