Leica M6 Classic of 1984
Leica M6 Electronic Prototype of 1981
This prototype came before the later fully mechanical Leica M6435. It featured the fully electronic Seiko shutter used in the Leica R4, along with TTL metering and automatic exposure control, similar to the later Leica M7435.
Leica M6 Prototype of 1983
This early prototype from 1983 bore the serial number and engraving of a Leica M4-P435. It featured electronic light meter mounted on a Leica M4-P body, which was in essence a hand-wired circuit board attached to the top of the camera to control the exposure mechanism. It featured a red dot with flat Leitz lettering and a brass top cover with recessed windows435 (like those of early Leica M2 cameras). The shutter speed dial had a different design, using a DIN/ASA scale with distinct lettering, and there was no "MADE IN GERMANY" embossing on the body covering435. There were two known prototypes of Leica M6 from 1983: one with the serial number 1621532, which was part of the former Leitz factory museum (inventory number 2308), and another with the serial number 1621534435.
The author of this website believed that one of these prototypes (likely 1621534) was displayed at the Leitz Museum in Wetzlar in 2026. The following detailed instructions for operating this specific prototype were handwritten on the tag attached to it:
~~~~~~~~~~~~~~~~~~
"PROTOTYPE OF LEICA M6
INSTRUCTIONS:
1 - SET FILM SPEED ON "DIN" DIAL
2 - SET SHUTTER SPEED ON THE OPPOSITE DIAL
3 - SLIDE THE RED SWITCH ON REAR TOP LEFT TO "ON"

5 - NOW TRIANGULAR RED LEDs ARE ACTIVATED. TURN APERTURE RING ON LENS IN THE DIRECTION OF THE TIP OF THE TRIANGULAR RED LED (OR TURN THE SHUTTER SPEED DIAL ON PANEL) UNTIL BOTH RED LEDS ARE LIT. CAMERA IS THEN SET FOR CORRECT EXPOSURE"

The same prototype was illustrated in Mr. Lars Netopil's "Museum Leica" book in 2018596.
Test Unit M6-RF
An interesting test unit of Leica M6 Classic was illustrated on page 28 of Camera Review No. 58 (Leica-Book '01), published by Asahi Sonorama (Tokyo)581. This unit, externally a chrome finished Leica M4-P, had its hot shoe engraved with "M6-RF"581. The camera had Leica M6 Classic viewfinder installed and didn't have the built-in light meter system581. It had a triangular mark, similar to that of Leica M6 Classic, in the viewfinder, indicating under-exposure581.
Production of Leica M6 Classic
In 1984, manufacturing was moved back to Wetzlar, leading to the development of the Leica M6 Classic341. The first Leica M6 Classic127 was introduced in 1984 with serial number 1657251355. This camera was essentially a Leica M4-P but featured a new TTL (through-the-lens) metering system that utilized center-weighted readings from a grey spot in the middle of the cloth shutter341. The design of the Leica M6 Classic was simple yet elegant, and it performed exceptionally well341.
When it was first introduced, the Leica M6 Classic was manufactured in Wetzlar, featuring a red dot logo that read "Leitz."341 In 1986, production moved to Solms, and the logo was updated to "Leica."341 In comparison to Leica M4-2, the Leica M6 Classic had a lighter and more affordable cast zinc top plate341. The camera had brass bottom plate341.
The early Leica M6 Classic cameras featured plastic inserts above the strap lugs to protect the body from wear caused by the camera strap435. The engraving "ERNST LEITZ WETZLAR GMBH" was found on the top plate of the camera435. It featured a 0.72 magnification viewfinder435.

Technical Specifications
The camera featured a built-in light meter127. Users manually adjusted the f-stops and shutter speed according to the guidance provided by diodes in the viewfinder127. The film speed could be set by turning an index disc located on the rear of the camera, with a sensitivity range from ASA 6 to 6400 in 1/3 stop increments127.
The camera's working range spanned from 1 second at f/1 to 1/1000 second at f/32127. It operated on two silver oxide button cells, each rated at 1.55 volts, or one lithium cell rated at 3.00 volts127. Fresh batteries typically lasted for approximately 20 hours with the camera continuously powered on127. For exposures metered at 15 seconds each, the batteries could support about 4,800 shots127.
A silicon photodiode with a collective lens was positioned inside the camera body at the top left, behind the bayonet127. This component captured light reflected from a 12mm circular bright spot located at the center of the first shutter curtain127. This spot accounted for approximately 13% of the entire film frame, and the metering spot represented about 23% of the viewfinder image as seen through the attached lens127.
All Leica M4-P winders could be used with the Leica M6 Classic127. Additionally, M4-2 winders with serial numbers 10350 or higher were also compatible with Leica M6 Classic127.
