Subject: [Leica] 21 mm Elmarit fringing

I have been using a pre-Asph 21mm Elmarit on the M8 and notice on the 
edges a subtle shift to light blue.

My assumption is that this may be caused by vignetting, but I may be 
wrong. Has anyone else noticed it.

A friend suggested that having the lens coded for the M8 might cure 
this problem. Does anyone know whether that is true or not?

My friend maintains that coding helps wide-angle lenses. True?

I assume the Asph 21 does not have this problem, but that's an 
assumption.

Your help is appreciated, as always.

Doug
