  What happened to the Lubi's? The focusing problem?

  Both methods will give you a closeup image
but I don't know if you can predict which will
work better without trying it.

  Regular camera lenses are designed to work
over a certain range of magnifications: usually
0 up to 0.1. Some lenses work well on extension
tubes and others don't. Some work better with
an good (achromatic) closeup lens than others.
I got good results with my Ricohflex using it
with the +11 diopter Pentax dental closeup lens.

  Since you (I?) can't predict how a 3 element
front cell focuser will perform as a macro lens
you may as well choose the method that you prefer
(is easiest) and implement that. Then shoot some
test shots.

  Does anyone with the Kingslake book know if
he says anything about 3 element macro lenses?
