Nice "experiment."

But I guess the only definitive conclusion is that new lenses in  
apparently pristine condition are better than hazy, scratched old  

But on a related topic, does the image quality ranking of older Leica  
lenses differ because of the reduced area of the M8 sensor? For  
example, the 35 mm Elmar is regarded as having good central  
definition but vignetting and poorer resolution toward the edges of  
the 35 mm frame. Many critics believe the Summitar is better than the  
Summicron in the central area but poorer in the corners. Even the  
Summar and the Hektor have good center image quality.  But since the  
M8 crops the image circle of the film lenses so that only the central  
area is used, have these old lenses gained a new lease on life?

How about it lens fans?
