Your lens is focusing past infinity (infinity being 600 to 900 times the
focal length depending on who you ask). The need to service it depends on
how much it bothers you.

Subject: [OM] Focusing at infinity - 75 / 150 zoom
|
| Today I became aware that my 75 / 150 no longer focuses at infinity at
| the infinity marker on the lens barrel. Focusing at infinity is about
| midway between the 30m mark and the infinity mark. By infinity I mean an
| object at least five miles away.
|
| As an interim measure I treated the focus at infinity as being when the
| split image in the viewfinder of my 4T was in perfect alignment even
| though the lens barrel had perhaps another millimeter to rotate before
| it would rotate no further.
|
| Can anyone advise me as to whether the lens should be serviced to have
| infinity set to infinity or whether what I have experienced today is
| normal behaviour for this lens.
