According to the Olympus sheet that came with my Zuiko 300mm from C.H. Ling,
the focussing beyond infinity is to account for thermal expansion, so Jim

Yes, my 300/4.5 and several other Zuikos also focus very slightly past
infinity. Confirmed it with a 2X-A and 300/4.5 aimed at a full moon one
night a couple years ago. It's never bothered me . . . I always check
focus even if it's on a mountain range 10 miles or more distant. John H.
put it well: "it's better to go 'beyond infinity' than to not reach it."
