This is a dumb question:  considering that old 50 Summicrons with coating 
damage and other early Leica lenses with "haze" easily visible to the naked 
eye with no special lighting required, produce sharp but low contrast images 
compared to  pristine samples, how hideous can the pictures be from these 
90's that have some haze you can't even see unless you hit it at just the 
right angle with a flashlight?  This survey is interesting and all (I have 
#2587xxx with tiny speckles on the *inside* of the *front* element, not the 
rear, but again only visible with oblique flashlighting) but has anyone ever 
shot one with a bona-fide case of foggy rear-element Skinny-Elmar-Disease 
against a healthy one and compared?  Does the haze affect the pictures or 
just the re-sale value?
