Regarding my need to get my eyes ck. sorry, poor conclusion from you all
that rather say it's my eyes than the lens.
Anyway after a few rolls of film through the Tamron 180mm f/2.5.
My conclusion is I need to remember to rely on the focus sharpness first
not the aperture stopping down to insure sharpness.
Zuiko 21 f/3.5 sharp with my eyes (using a 1-2 or 1-13 screen)
Zuiko 50 f/1.4 sharp with my eyes (using a 1-2 or 1-13 screen)
Tamron 400 f/4 sharp with my eyes (using a 1-2 or 1-13 screen)
Tamron 180mm f/2.5; not completely sharp no matter what distance, having
to rely on stopping down the aperture to get anything right.
No matter what focus screen either.
So it's back to KEH or Tamron for repair.
I do note the 180mm slides have a lack of tolerance to critical focusing
outside the main subject.
