Took out the Yashinon and made a few shots. Clickable for full size:

Nice vintage character, and good pop and (central) sharpness wide open.
Stopped down to f/5.6, nice:

The lens takes some stopping down to get really sharp from corner to corner. But @f/8, it is very sharp indeed:

Conclusion: I bought this lens because of its looks, and because I like lenses with cm designation 
But it is quite capable as well. Very usable wide open, with vintage character, and sharp all over when stopped down. |

It's the same as the early AUTO Mamiya/Sekor 55mm 1.8.
I took them apart side-by-side and the elements were interchangeable. The only difference, apart from the cosmetics, which I agree are very nice in the case of the Auto Yashinon, was the way the rear block was mounted. As I recall the rear block of the Mamiya Sekor was easier to unscrew.
It's a pretty great lens, whatever its livery or housing. |

The main difference against Yashinon-DX 1.7/50 seems to be a more painterly bokeh of the older lens. Very attractive. |

Good question. I'v never opened Yashinon-DX. Pretty sure there will be a more competent reply to this question. |

This is the DS 50mm 1.7 (same as the DX but just automatic and not manual aperture)

Nice shot! I found out that I was using my Yashinon-DX for street shooting mostly, so too little for close-ups. This situation should be fixed. |
