I see the out of focus.  Every place is out.  Before making conclusions, you 
must see if the test was "fair".

1) Was the lens properly focused?  You need to take several clicks on the 
same subject, using a tripod and cable release.  Focus
each time separately.  You should also use the mirror lock up feature to 
keep vibration down.  Is the image put down on film in
focus?  You judge this step using a magnifying glass and your eyes.

2) Is your scanner properly focusing on the image plane?  Use something like 
a focusing negative target to judge this step.

3) If everything is properly working, and all the focus error possibilities 
are taken into account. Try the test again.
