  ok everyone,
  The results are in.This sawblade lens needs further testing.As far as i
can
  tell ,i am getting many images side by side.I guess this is partly to do
with
  diffraction?Am i right?
  Anyways i ran out of time today and it was raining.i used up a bunch of
  film,and i am getting closer to a usable image :)Here is an interesting
  observation though!
  The horizontal lines in the image seem pretty sharp.But the verticals have
  about 7 lines for each single line.
  Any ideas?
  Harry
