I just checked it with another lens (135mm) and the problem's there too :-(
Is there any fix besides a CLA?

e: Ex: Infinity Focus problem
Simon,
You may want to check to see if your other lenses are focusing to infinity
with your camera to rule out mirror misalignment. Or put the lens on
another body to check as well.
If the mirror is misaligned on the body, you will have focusing
inaccuracies; especially
lens (shallow depth of field).
Regards,
Jose R. Rodriguez

I am going to take a few pics and see if it does.
Thanks for the information.

Bob,
The lens I am having the infinity focus problem with:
focal length: 35mm
I have to move the focusing ring back, so instead of being on
the infinity mark, it is between infinity and the next mark,
which happens to be 15 ft.

I think the word 'setting' should be emphasized, in your statement below.
Why do you believe that to be true ~ to account for the lens

Hi all,
I have a lens that is little off when attempting to focus to
infinity--instead of moving the focus all the way to the end,
you have to back it off a little. It is only with this one
lens and not a problem of the camera with other lenses.
