Mainline Photographics currently puts this legendary manual-focus babe on sale. Optically this outperforms the Zeiss Loxia 50mm F2 counterpart. Detailed technical review can be found here:

To sum up, it truely deserves its "apochromatic (APO)" claim with almost non-existing CA or LoCA. It even achieves an extremely even optical performance from corner to corner in full-frame system at wide-open F2 already. The only downside I can think of is its min. focus distance is a bit longer compared to other 50mm lenses. Otherwise, enjoy.
pretty expensive for manual lens… at this price id expect F1.2 like those crazy Voigtlanders for M43…
