LEICA M5

Name: Leica M5
Brand: Leica

The Leica M5 is a 35mm rangefinder camera produced by Ernst Leitz GmbH from 1971 to 1975. It represents a significant, albeit controversial, departure from the traditional M-series design, introducing through-the-lens (TTL) center-weighted metering and a larger, more ergonomic body aimed at professional photographers seeking advanced exposure control in a rangefinder platform.

Overview

Introduced in 1971, the Leica M5 was developed during a period of intense competition from Japanese SLR manufacturers offering increasingly sophisticated through-the-lens metering and faster operational workflows. Leitz sought to modernize the M-series to retain its professional user base, particularly photojournalists and reportage photographers who demanded accurate exposure feedback without sacrificing the compactness and quiet operation of rangefinders. The M5 was the first M-series camera to feature built-in TTL metering, a major technological leap that required a complete redesign of the internal layout and viewfinder system.

The M5’s larger body—significantly bulkier than the M2, M3, or M4—was engineered to accommodate the metering circuitry, a larger viewfinder with integrated exposure information, and a redesigned film advance mechanism. Despite its advanced features, the M5 was met with mixed reception. Its departure from the minimalist M-series aesthetic, unconventional control layout (including the placement of the shutter speed dial on the front left of the top plate), and high price alienated many loyal Leica users. Nevertheless, the M5 laid the groundwork for future electronic M models and remains a pivotal model in Leica’s evolution toward electronic integration.

The M5 was produced exclusively at the Leitz factory in Wetzlar, West Germany, with approximately 35,405 units manufactured during its four-year production run. It was succeeded by the M4-2 in 1977, which returned to a more traditional mechanical design but retained some ergonomic improvements pioneered in the M5. The M5 was intended as a direct competitor to high-end SLRs like the Nikon F2 and Canon F-1, offering TTL metering in a quieter, more compact rangefinder form—albeit at the cost of some traditional Leica design principles.

Key Features

First Leica M with TTL metering: Utilized a cadmium sulfide (CdS) cell to measure light through the lens, providing accurate exposure readings under varying lighting conditions.
Integrated exposure display: A needle visible in the viewfinder indicated correct exposure when aligned with a fixed mark, linked to a meter coupling lever on the lens.
Larger, ergonomic body: Designed to improve grip and accommodate internal electronics, with a reshaped top plate and redesigned rewind crank.
Improved viewfinder brightness: The 0.72× magnification offered a brighter, more detailed image than earlier M models, with automatic frameline selection via lens cam.
Stop-down metering system: Required lenses with meter coupling levers (e.g., Summicron 50mm f/2 DR, Summilux 35mm f/1.4 ASPH); non-coupled lenses required external metering.

Historical Context

The Leica M5 was launched at a critical juncture in photographic history. By the early 1970s, Japanese manufacturers like Nikon, Canon, and Minolta were dominating the professional market with advanced SLRs featuring TTL metering, motor drives, and interchangeable finders. Leitz, traditionally conservative in its engineering philosophy, faced pressure to innovate while preserving the core values of the M-series: precision, discretion, and optical excellence. The M5 was Leitz’s response—a bold attempt to merge rangefinder simplicity with modern exposure technology.

Despite its technical merits, the M5 was commercially underwhelming. Its unconventional layout, including the front-mounted shutter speed dial and recessed film advance lever, confused long-time Leica users. The removal of the accessory shoe (replaced by a fixed hot shoe with integrated meter contacts) limited accessory compatibility. Additionally, early models suffered from meter instability and battery compatibility issues (originally using the mercury PX625, now obsolete). Critics also noted that the larger body compromised the compactness that defined the M-series ethos. As a result, the M5 was discontinued in 1975 after fewer than 36,000 units were produced, making it one of the rarest and shortest-produced M models.

Collectibility & Value

Today, the Leica M5 is a sought-after collector’s item, valued for its historical significance and rarity. In excellent working condition, M5 bodies typically sell for $3,500–$5,500 USD, with pristine, low-count examples commanding higher prices. Collectors prize the M5 as a transitional model that bridged the gap between mechanical and electronic Leicas. Original boxes, manuals, and accessories (particularly the rare M5-specific leather case) significantly enhance value.

When purchasing an M5, buyers should verify the functionality of the meter, as aging CdS cells and corroded battery contacts are common issues. The camera requires a 1.35V mercury battery (PX625), though modern substitutes (e.g., Wein Cell or adapters for 1.5V batteries) can be used with exposure compensation. Other common problems include sticky shutter curtains, worn film advance mechanisms, and misaligned rangefinder calibration. Due to the complexity of the metering system and scarcity of parts, repairs should be performed by experienced Leica technicians.

Repair & Maintenance

The Leica M5 operates on a 1.35V mercury PX625 battery, now obsolete. Modern alternatives include zinc-air batteries (e.g., Wein Cell MRB625) or voltage-regulated adapters for 1.5V alkaline batteries, though the latter may require exposure compensation of -1/3 to -2/3 EV. The CdS meter cell degrades over time and may require recalibration or replacement by a specialist. Common mechanical issues include shutter timing inaccuracies at slow speeds, film transport slippage, and rangefinder misalignment. Due to the complexity of the meter linkage and limited availability of original parts, repairs are best handled by certified Leica service centers or experienced independent technicians. Regular CLA (Clean, Lubricate, Adjust) servicing every 5–7 years is recommended to maintain optimal performance.
