The ZM line are lenses made for the Leica M mount and for the new Zeiss Ikon camera. They are also compatible with other rangefinder camera bodies with M Mount e.g. the Konica Hexar RF (KM Mount), the Cosina Voigtländer Bessa RxM/RxA series (VM mount), the Rollei 35RF and the Epson R-D series. Some lenses are manufactured in Germany by Zeiss, some in Japan by Cosina. -Wikipedia
We are currently in the process of preparing our Carl Zeiss Lens Guide, where we will list a guide to our favorite Carl Zeiss lenses. We plan to review one lens from each general category and focal length, from macro, to 50mm, to zoom lenses, wide angle lenses, portrait lenses, and more! Check out our first edition of the Lens Guide Series, our guide to the Best Leica Lenses.
