As a person that is trained as a scientist.  You may want to qunatify, 
your photographic experience.  But, in reality I can probably save you 
a lot of time.  Leica Lens as a general rule test poorly.  In 
comparsion to the other other major manufacturers.  What you have to do 
is to take pictures and see with the different lens and see what you 
really like.  Leica lens are designed to reproduce a scene while 
maintaining, the proper contrast ratios.  While other lens are designed 
to reproduce charts and graphs, Leica's tend to photograph life , the 
way it's supposed to look.
