[1] In 2022, Leica introduced a new version of the M6, based on the technology of the Leica MP, but staying true to the design of the M6.

The light meter was operated by depressing the shutter halfway, had no moving parts, and used LEDs to display readings in the viewfinder.

The top and bottom plates were made from lighter, cheaper magnesium alloy rather than the heavier machined brass of the M3 and M4.

The M6 and M6 TTL are mechanical cameras; all functions except the light meter work without batteries, unlike the succeeding M7, which needs electrical power to operate properly.
