Leica may restrict access to hidden M10 and M11 service menus
A hidden service menu is available on Leica M10 and M11 cameras, as well as the M (Typ 240) and models in those lines.
It can show details such as battery capacity and the total number of photos taken, which may help people assess used cameras.
Leica says the menus are for technical diagnosis and servicing, not normal use by camera owners.
Some users say changing menu options has left camera displays unable to turn on.
Leica warns that changing internal settings can affect camera operation and advises users without technical knowledge to stay out of the menus.
The company says a future software update could add safeguards or change access, but it has not said when or whether that will happen.
Leica says it may change access to hidden service menus on the M10 and M11 or protect them with additional safeguards.
The menus are intended for technical diagnostics and servicing, and Leica advises users not to access them or change settings without appropriate technical knowledge.
Some users on Reddit report that camera displays stopped turning on after they changed service-menu options.
The menus can show information including remaining battery capacity and total photos taken.
Leica says battery information is not in the regular menu because it aims to keep the user interface uncluttered.
