I got one in Contax mount last year which I use infrequently, mostly 
night-time and wide open. I like it, but do not often use the Contax 
(or 50s). This sample has what looks like partial separation of some 
lens elements, this has no definite effect on the images. I have not 
noticed flaring. I use it with  a not so nice rubber lens hood - I 
tried a nicer metal hood which fits a 2.0 Sonnar but not this one, 
perhaps the thread is damaged or less standard. This Sonnar is a later 
coated type and I am curious to try the earlier (only stops down to 
f/11) uncoated version.
