I too have checked my Zuiko collection: All the fixed focal lengths have
an IR focus mark. However on most the IR mark coincides with one if the
DOF markings, which is red instead of black. The ones I have checked are:
24mm/2.8 (DOF mark), 28mm/3.5 (DOF mark), 35mm/2.0 (DOF mark),
50mm/1.8 (DOF mark), 50mm/1.4 (DOF mark), 50mm/3.5 macro (DOF mark),
85mm/2.0 (DOF mark), 100mm/2.8 (DOF mark), 200mm/4.0 (separate dot)
and 300mm/4.5 (separate dot).
The zooms, 75-150mm/4.0 and 28-48/4.0, do not have an IR mark.
It would appear that there are variants, re. Tomoko's 50/1.8 and 100mm.

Lars
