[Leica] 21 f/4 R Super Angulon's performance and compare with the new 19mm Elmarit.

["Martin H. Krieger" <krieger@usc.edu>]

For those who have experience with the 21 f/4 R Super Angulon, and those 
with with new 2.8 19mm R--

1.  I shot some pictures recently of flat material at about 30".  I found 
the corners (and the long side) went quite soft, at f/4.  This was stuff 
like maps, so you could see it lose sharpness.  Is this simply a matter of 
needing to stop down?  Would the new Elmarit be much better?

2.  I also shot some images with the sun coming at me, albeit at the edge. 
 I got sort of 4 sided reflected images.  Perhaps my Super Angulon is old 
enough not to be multicoated, if they ever were.  Is the new Elmarit much 
better?

For my ordinary outdoor shooting, none of these come up and I am quite 
happy with the lens.

Thanks,
Martin
