Physical casing was redone. Optics were recoated and the tolerances supposedly tightened but in our experience real world performance was only modestly increased and the sample-variation which plagued the 45mm (one would be terrible, another good, and another very good) was still present in the Phase branded version - possibly less so, but hard to say conclusively without more total samples.
It's not a bad lens, but it was not what we hoped for when the lens was announced.
