Description:
AUTO YASHINON® DS-M TOMIOKA, which was produced within the years 1973 to 1974 for approx. 6 months in a very low quantity.
The most important innovation about this lens is, the remarkable fact, that it is one of the worldwide first computer calculated lenses.

"For taking pictures in evening light and night scenes the AUTO JAPAN TOMIOKA® 55mm F=1.2 has been created."

I own this lens since last year for about 500usd in Mexico. I consider it absurd that it is being sold in about 1100usd to 1350usd on ebay.

I'd glued the aperture pin and I'd glued the original pentax M42 to K adapter in order to prevent it to fall from the camera; then replace the orginal focus rubber using a pentax rubber; I hope that if something is going to drop is the reselling price Yes, I'm a criminal, but it's criminaly practical also

Sharpness, wide open, is not as good as the Pentax-K 50mm 1.2 but the bokeh is unique.

Aberrations disapears closing two clics the aperture.

Edited to add a this note: very easy to focus. There's is a narrow gap between the 10m and infinitum, that's is "bingo" if you nail manual-focus in that area (check last pic), use live view and focus peaking to get best result.
