As far as I know, the AF 55/2.8 has the same optics as the AIS version. Since the optics are the same, I expect the AF 55 micro will perform as well as the AIS version - brilliantly. The AIS lens can go to 1:2, and requires the PK-13 extension tube to go to 1:1. The AF lens has a completely new mount, which permits it to go to 1:1 without the PK-13. It also has a larger 62mm thread. This was one of the first AF lenses, so the focusing ring was rather narrow and loose-feeling. The 60/2.8 has a new optical design and mount.
