my new 350D back foucs with 70-200 4L at 200mm about 1cm. It can be observed at 5.6F easily, is it acceptable? Can it be changed?

It is very likely that the lens has problem. My friend also has the same problem with 70-200 4L when putting on 300D. Bring the whole set of gear to Canon service centre for checking and re-tuning.
