Yup. The Duonar makes a circular image on the
negative and does not provide full frame
coverage. So what? That can be fixed in the
darkroom. It is a nice and sharp lens worthy of
merit despite its circular image. The Magnar is
also quite fine though I am selling off my Bayo I
stuff so I might have to be selling it as
well. You might be stirring enough for me to
shoot a roll, six on the Duonar and six on the
Magnar and, once I find a place which still
processes 120, to scan the images for your
review. Allow me to do the following: one shot
normal, one shot with Magnar, one shot normal,
one shot Magnar, and so forth. The results are
of rather astonishing quality. Now, the Mutars
are even better. Bob Pins could say more on that subject.
