| Designation | Leica M6 |
| Camera type | Analogue rangefinder system camera (35 mm) |
| Type No. | 2248 |
| Order No. | Black: 10 557 |
| Material | Closed full metal housing, Top cover and bottom cover: brass, black finish |
| Lens mount | Leica M bayonet |

| Dimensions | 138 x 40 x 77 mm |
| Weight | 575 g (without battery) |
| Viewfinder | Large, bright-line rangefinder with automatic parallax compensation |
| Parallax compensation | The horizontal and vertical difference between viewfinder and lens is compensated automatically in line with the relevant focus setting. Congruence of viewfinder and actual image. The size of the bright-line frame matches the distance: – at 2 m: the exact sensor size of approx. 23.9 x 35.8 mm – at infinity: (depending on focal length) approx. 7.3% (28 mm) to 18% (135 mm) – less than 2 m: less than film size |
| Viewfinder magnification | x0.72 (all lenses) |
| Wide- base rangefinder | Split and superimposed image rangefinder shown as a bright field in the center of the viewfinder image. |
| Shutter | |
| Shutter type | Focal plane shutter with rubber liner, mechanically controlled |
| Shutter speeds | Mech. shutter: 1 s - 1⁄1000 s Flash Synch: up to 1⁄50 s |
| Shutter release | Two-stage: Power up (activation of exposure meter) – Release. Integrated standard cable release thread. |
| Film winding | |
| Loading | Manual with quick wind lever or LEICAVIT M, motorized with LEICA MOTOR-M, LEICA WINDER-M, LEICA WINDER |

| Focusing | |
| Working range | 70 cm to ∞ |
| Focus mode | Manual |
| Exposure | |
| Exposure metering | TTL (exposure metering through the lens), with working aperture |
| Metering cell | Silicon photo diode with convex lens to the top left behind the camera bayonet. |
| Film speed range | Manual setting from ISO 6/9° to ISO 6400/39°. |
| Metering principle | The light reflected by a metering spot in the center of the 1st shutter curtain is metered. The metering spot has a diameter of 12mm and therefore corresponds to approx. 13% of the full negative format or around 2/3 of the short side of the corresponding frame in the viewfinder. |
| Exposure control mode | Manual shutter speed and aperture setting, adjustment using LED light balance. |
| Flash | |
| Flash unit connection | Via accessory shoe |
| Synchronisation | On the 1st shutter curtain |
| Flash sync speed | 1/50s; slower shutter speeds possible. |
| Flash exposure control | Via computer control of flash unit or via guide number calculation and manual setting for the required aperture. |
| Power Supply | 2 Silver oxide button cells (PX76/SR44) or 1 Lithium battery (DL1/3N) |
