Bill,

What means CA? Chromatic Aberration?

Could you share an image as I have no idea what to look for in this matter.

How to put it in evidence?

Xavier,
Interesting thread (to me anyway). I have had a 24 Elmarit for years. On a R3 it was great but on my 20d it doesn't work well at all. It is OK in the center but by 1/3 out it is very soft and the edges show lots of CA. With a 1.6 crop sensor and a Leica lens, this shouldn't be. I don't know if the problem is the adapter, unknown to me the lens has been damaged, or if this lens is just not a good match for a digital sensor. My 50, 80, or 180 all work fine with the same camera and adapters. Anyway, I wish you better luck than I have had; I like the lens too. 

Bill
