Starting here you can dig deeper into the different eras of Yashica lenses.
From the early beginnings with the Pentamatic and the (solely then) featured Y-Bayontt via M42 thread mount Super Yashinons, the DX-series starting with the TL up to the DS- and DS-M-series of the last M42 models.
Going on with the C/Y-bayonet lenses of the ML, MLC, MC, DSB and YUS series you will end with the (not too big) offering of lenses for the Y/AF mount.
There’s a question mark on the origin of the 35mm Yashikor lenses, if you know some more information on this topic please feel invited to share it!
The same, of course, applies to corrections and addenda to the other articles :-).
