The lenses of the Leica M-System are arguably the best 35 mm lenses in the world. Thanks to the M-Adapter T, more than 20 of them can also be used with the T-System. The sensor for six-bit coded M-Lenses ensures that the Leica T knows which lens is mounted and can provide full support for functions like exposure metering, aperture priority exposure and manual control. Retails for over twice the price.
