I have not. However, KEH needed to replace my first two SQ-Ai bodies under warranty and the optical performance of the 80mm PS lenses did not change with the body used.

In any case, the performance of the 80mm PS lenses - while not really satisfactory - was far better than the 150mm S lens. So it does not appear to be a general issue with body alignment.

I don't know if these optics suffered some sort of trauma during their lives (KEH Bronica gear tends to come from professionals - implying heavy use) or if the quality control (both in the Zenza and Tamron regimes) was just that lousy.
