Leica Lens vs Nikon Lens

[seungmin@luxmail.luxcom.com]

     As one of Leica aficionados, I have been surprised at the test results 
     of some of the photo magazines like Popular Photog or Modern Photog.  
     Their test results of Leica lenses compared with those of Nikon or 
     Contax lenses, were not so impressive, specially when I think about 
     the price.  For some reason, they have been favorable to Nikon a lot.  
     This sometimes made me stop and think if Leica lenses were really 
     worth the money compared with Nikon or Contax lenses.  What is your 
     opinion?  What makes Leica lenses so expensive other than the superb 
     silky smooth barrel finish, when compared to Nikon and Contax lenses? 
     I am talking about the lens quality which determines the quality of 
     image.  Thank you.
