Leica just updated a huge number of its M cameras for a lens that only 660 people can own

Leica has released firmware updates for a wide array of its M cameras, including both M10 and M11 generations, with the primary addition being support for the newly released Leica Summicron-M 66 f/2 lens. This lens is part of Leica's Classic Line and is one of the most exclusive modern M lenses, with only 660 units produced worldwide.

The firmware update is available for several camera models in the M11 and M10 families, with the M11 models receiving firmware version 2.6.4. The M10 generation cameras also receive firmware updates, with the specific versions varying depending on the model. The addition of the Summicron-M 66 f/2 lens profile in the firmware update highlights Leica's commitment to supporting older camera models with new lenses.

While most Leica M owners are unlikely to own a Summicron-M 66 f/2, the update ensures that their cameras are ready for such a rare lens should they ever come across one.
