I'm certain it will be better than nearly any 50/2 out there, if the past APO Lanthars are any indication of what Cosina is capable of. But at 1/7th the cost of a Leica, there's got to be some compromise somewhere. The 50 APO is one of the most remarkable lenses I ever used, second place going to the Voigtländer 2,5/125.
