A means ULD glass, like the 120/4 A macro vs a true "APO" white (in MF 645) lens like the 200mm, 300mm and 500mm APOs.
People often refer to the 150/2.8 A and 120/4 A as "APO" and while they do an excellent job at CA control, they are not technically an APO lens - at least as Mamiya (vs 1001 armchair experts) defines it. Owning the 150/2.8A - I'd agree with JC - it is a VERY nice hunk of glass.
