Leica Thread Adapter & New Correction Lenses
The thread adapter is supplied with a special tool for mounting it on the camera. Once mounted, Leica correction filters from previous M cameras with smaller diameters can be mounted on the M10. The Thread Adapter also enables the use of the Leica Anglefinder M and the viewfinder magnifiers on the Leica M10. The thread adapter and mounting tool are supplied in a Leica SD case for safekeeping when not in use.
