Leica Summicron 2/5cm Leica M 1952 - Possibly Pre-Series, Serial Number 1041050
The Leica Summicron 2/5cm M bearing serial number 1041050 is an extraordinary collector's piece. According to available Leica production records, this serial number dates to 1952, yet the first Leica M camera was not officially introduced until 1954. This discrepancy suggests the lens may originate from an early pre-production series assembled before the official launch of the M system. A second ring mounted above the lens designation ring, not found on regular production Summicron 5cm M examples, further supports this hypothesis. The lens is in good external condition with light signs of use. The glass is clean with light cleaning marks and minimal internal dust, both without influence on image quality.

Features of the Leica Summicron 2/5cm M - Possible Pre-Series 1952
The Leica Summicron 2/5cm M with serial number 1041050 presents two characteristics that set it apart from regular production examples. First, the serial number dates to 1952 according to available Leica production records, two years before the official introduction of the Leica M camera at Photokina 1954. Second, an additional ring is mounted above the designation ring, a feature not present on standard Summicron 5cm M production lenses. Taken together, these details make this Leica Summicron 2/5cm a potential pre-series example whose precise production history invites further research. For Leica collectors and historians of photographic technology, this lens represents a rare opportunity.

Frequently Asked Questions
- Why does the Leica Summicron 2/5cm M carry a serial number from 1952 if the M camera was only introduced in 1954?
