Mount and adapters for the 55mm f/1.8 EBC
The Fujinon 55mm f/1.8 EBC has a native M42 mount. M42 is a 42mm x 1mm screw thread with a 45.46mm register, introduced in 1949 on the Contax S and later adopted by Praktica, Asahi Pentax, Fujica, Zenit, Yashica, and Chinon. Every mirrorless mount has a shorter register than 45.46mm, so a plain mechanical adapter puts the lens at its design distance and infinity focus is preserved. Plain threaded adapter, no optics. Lenses with an auto-diaphragm pin need either an Auto/Manual switch on the lens or an adapter with an inner flange that holds the pin in. Preset lenses such as the Helios 44-2 have no pin and work on any adapter.
