LEICA M6
The Leica M6 is a 35mm rangefinder camera introduced in 1984. It was the first metered Leica M-series camera with through-the-lens (TTL) center-weighted light metering. It keeps the mechanical precision and optics of the M-series and adds exposure help. Professional photojournalists and enthusiasts who wanted reliability and simplicity favored it.
Overview
The Leica M6 grew directly out of the Leica M4-2 and M4-P. Photographers wanted built-in metering in a manual camera system, and the M6 gave it to them in 1984. It kept the mechanical robustness, compact size and optical quality of its predecessors and added a TTL metering system - a feature long requested by photographers who used Leica rangefinders in fast-paced work like photojournalism and street photography. The M6 came with either a 0.72x or 0.58x viewfinder magnification. The 0.72x version was optimized for 35mm and 50mm lenses, the most commonly used focal lengths in documentary photography.
The M6 was aimed at working photographers who valued precision, durability and discretion. It kept the M-series mechanical shutter and manual focus via coincident-image rangefinder. It added a bright-line viewfinder with LED exposure indicators - two red arrows that guided the user to correct exposure by aligning shutter speed and aperture settings. That cut the risk of exposure errors in variable lighting and left the deliberate shooting style of classic Leica cameras alone. The M6 stayed in production for 14 years, until the M6 TTL succeeded it in 1998.

- LED Exposure Indicators: Twin red arrows in the viewfinder guide shutter speed and aperture adjustments for correct exposure.
- 0.72x Viewfinder: Optimized for 35mm and 50mm lenses, with bright-line framelines automatically selected by lens cam.
- Mechanical Shutter Reliability: Fully mechanical operation at all speeds; functions without batteries for shutter speeds 1/60 sec and slower.
- Compact and Durable Build: All-metal chassis with brass top and bottom plates, designed for long-term field use.
Historical Context
The Leica M6 arrived when autofocus SLRs were taking over the consumer and professional markets. Nikon (F3, later F4), Canon (AE-1, T90) and Minolta (Maxxum 7000) were pushing automation and electronic integration. Leica went the other way and stuck with the mechanical rangefinder, refining it for a small but dedicated user base. The M6 was not a leap in automation. It added metering without giving up the M-series emphasis on simplicity, precision and optical excellence.
The M6 filled a real gap. Before it, photographers using the Leica M4 or M5 had to rely on handheld or external meters. The M5 (1971) had built-in metering but was large, complex and unpopular next to the lean M4. The M6 put metering into a compact body with the familiar M4 form factor. Photojournalists received it well, including Henri Cartier-Bresson (who switched to the M6 late in his career) and Sebastião Salgado. Its reliability in extreme conditions and quiet operation suited candid and documentary work.
Collectibility & Value
Today the Leica M6 is one of the most sought-after film cameras on the used market. Models from the 1980s and early 1990s in good working condition typically sell for $3,000 - $5,000 USD. Black paint variants and rare editions (e.g., M6 0.85x for 28mm/35mm/75mm/90mm) command premiums up to $8,000 or more. The 0.72x version is the most desirable because it works with standard lenses and has the brighter viewfinder.
Before buying an M6, check the meter, the shutter speeds and the rangefinder alignment. Common problems are degraded light seals, sticky shutter curtains (especially at 1/1000 sec), and failing meter circuits from aging components or battery leakage. The camera uses a single 1.55V mercury battery (now obsolete) or a modern 1.5V silver oxide cell (e.g., Duracell 521/625U) or zinc-air alternative. The zinc-air cells may affect meter accuracy because of the voltage difference. Some technicians retrofit cameras with meter recalibration or voltage regulators for consistent performance.

Repair & Maintenance
The Leica M6 uses a single 1.55V mercury PX625 battery (or a modern SR44/SW mercury-free equivalent), though voltage differences can throw off the meter. A common fix is a Wein Cell (zinc-air battery) or a voltage-stabilizing adapter to keep the meter response consistent. The mechanical shutter needs CLA (clean, lubricate, adjust) servicing every 5-10 years, depending on use. Common failure points are the shutter's rubber damping material, which hardens over time, and the rangefinder's cam mechanism, which can wear or misalign. The camera is mechanically complex and built to tight tolerances, so repairs should go to qualified Leica technicians or specialized repair shops. Replacement parts are still available through Leica's heritage service.
