Uh oh, here we go again...
Olympus made enough changes during production of the 1.8 to have 5 different
parts lists, though some changes were as simple as Type 3 (sayting MC on the
name ring, front element part of filter ring assy, to Type 4 with same front
element w/ filter ring but NO MC on the name ring (still multicoated
though).
