Most all rangefinders, fixed lens and others (read 'expensive, starts with
"L"...) seem to focus only to about 3 feet or 1 meter. Closer than that and
parallax starts to be a significant problem with the offset view through the
rangefinder window.

A long time ago some of the manufacturers made what are called "Auto-Up"
closeup lenses, which incorporated the actual closeup lens and a
wedge-shaped glass panel which fit in front of the finder windows and 'bent'
the view to more closely match the actual area of the image. These seem to
be kind of hard to find, and I don't think they were made much after the
1950's, so no specific Olympus 35-SP version was ever made so far as I know.
I've seen Konica and Canon versions on e*ay on occasion, usually described
as fitting some model from the mid to late 1950's.

I think at one time Kodak offered a rig which comprised a closeup lens and a
pair of metal wire arms which screwed to the tripod mount. The arms extended
at an angle 'down and away' then had two uprights. When mounted and with
the lens focused to a specified distance the uprights were just outside the
left and right edges of the image area, and at the right distance... so if
you centered the flower (or whatever...) in between the uprights you were in
focus and in the center of the film image.

I suppose you could experimentally create something like this for the SP,
with duct tape, JB-Weld, epoxy and bailing wire... see if Walt can help you
some. <g>
