A lens I have been resisting to buy, with the hope of AF version surfacing. But that is probably not going to happen until next year (again). So far the impression is softer and lower contrast f1.4, but very good already at f2. Shooting at infinity requires stopping down to f5.6, otherwise the curvature of the field (heavier than the Noct) will render corners soft. However, once stopped down this lens is indeed super sharp.
