Dante,
The best way to focus the 75 is to initially set the lens to either infinity
or closest focus depending on what you typically focus on; if typically less
than 5 meters then start at nearest point.  Then find an edge in the plane
of focus, say the iris of an eye.  At a medium speed turn the focusing ring
until the two images just come together and stop.

My 75 is pretty d*&mn sharp in the center 1/3 to 2/3 even wide open so no
other sharpening than normal.  The contrast compared to the new designs is
less so you might adjust your curves to fit or enjoy the slightly smoother
look.  YMMV.

My 75 front focuses about four inches at 2meters so I adjust focus
accordingly, just have not wanted to send the lens off just yet.
