From the editor

Standard lens for any Leica screw mount camera. It was developed by a small Japanese company Yasuhara Manufacturing Co. Ltd., founded by Mr. Shin Yasuhara, a former employee of Kyocera, in November 1997 and existing until February 2004. The barrel is made entirely of metal. Optically, the lens is based on the classic Tessar design and has a multi-layer anti-reflective coating.
