Made by Tomioka Optical of Tokyo, Japan for Yashica. Yashica “allowed” a few of their Auto Yashinon 55mm, f/ 1.2 lenses to also carry Tomioka’s name. This is a M42 mount lens.
The serial number (lowest found so far) decodes to – No. 5520128 which is ‘552’ is the lens model number (55mm f/ 1.2) and the ‘0128’ is the production sequence number. 128 being the 128th lens made.
These super lenses in excellent condition bring around $800 to $1200 depending on the goodies that might be included (front and rear caps, case) and what not.
