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 when you open up the lens (shallow depth of field). Regards, Jose R.
