Oly 150mm f2.8 Macro?

Sounds like a great lens for nature and wildlife. Wonder if it will focus down to 1:1 magnification and what the front element lens-to-subject distance is?

I have an old Vivitar Series 1 90-180mm flat-field macro zoom (circa 1975) that will continuous focus to 1:2 magnification (at 180mm focal length) at a range of 2 ft from front element lens-to-subject distance....handy when photographing stinging insects or temperamental reptiles.
