[Leica] 400mm f6.8 Telyt problem

[len-1 at comcast.net (Leonard Taupier)]

Hoppy,

I may have a couple examples my son sent me. He did illustrate before  
and after pics. If I don't have examples I can have him e-mail me  
some. I saw the vignettes were in the extreme corners in clear blue  
sky as you describe. I'll also ask my son if he added any filters  
that would aggravate the problem. Your examples are not nearly as  
severe as his. Give me a couple hours. Dinner is waiting.

I will gladly hand carry all my gear for you to test. Will only  
charge shipping.  ;-)

Cheers,
Len
