I did a little more Googleing on the lens. All the f2.8 are MC. This is a later version and by then they dropped the MC on the front of the lens.
The later ones didn't say MC. They just says Japan (not made in japan, just japan) on the front ring. Those are multicoated and are the last version. I have two of them. Very nice lens.
