[Leica] DMR: Hands on

[Frank.Dernie at btinternet.com (Frank Dernie)]

Well it seemed to me that the fact that the completely different amount 
of vignetting by the CV and Leica 21mm lenses suggested that the 
vignetting  was due to the lens geometry as much as the focal length. 
If this is the case then the supplied correction software will correct 
for the lens it is meant to, but not necessarily any other of the same 
focal length but different exit pupil position, for example. That means 
if I bought one I could correct for errors due to a Voigtlander 21mm, 
which I don't own, but not a Leica 21mm which I do own.
I had intended to buy one but now I have cold feet! I guess it is fine 
if all your lenses are the CV ones.
The other concern i have with correction of this type is that I can 
only see how it can take place at the expense of dynamic range.
