My first concern was that the camera might be like the OMs which have a
-2 diopter correction built into the viewfinder. When buying an OM
branded correction lens you purchase what is labeled for your
prescription. For example, if your prescription is +2 diopters, the OM
lens will be labeled +2 but its actual optical power will be +4. The +4
along with the -2 of the viewfinder will result in +2 final correction.
Although Nikon 19mm correction lenses will fit the X-Pro1, the info I
found on the web says that old Nikon bodies actually have a -1 built-in
correction. Therefore, I suspect (but do not know) that Nikon diopter
correction lenses are probably like OM correction lenses and a lens
labeled as +2 is probably actually +3.
The X-Pro1 owner's manual says on page 98 "COSINA Diopter adjustment
lenses are recommended for this camera." Doing a Google search with
[ cosina diopter adjustment lenses price ] returned a lot of info rich
sources including the tip about Nikon correction lenses above.
Some of the best came from TOP
<http://theonlinephotographer.typepad.com/the_online_photographer/2012/10/diopters-for-the-fuji-x-pro1.html>
which says the X-Pro1 does not have any built-in correction in the
viewfinder. That means the correction lens you should use is exactly
the same power as your prescription. I quote
-----------------------------------------------------------------------
Jim Gamblin: "B&H has the Fuji diopters for $14.95. also Voigtlander
diopters will worko on the Fuji X-Pro1, maybe a little higher priced.
[Stephen Gandy sells those—thanks to Bill Lewis for that. —Ed.] Look for
19mm thread. Unlike the Nikon diopters, buy the others to match your
perscription. After putting a +2 (just like my reading glasses) on my
X-Pro1 it felt like a new camera—worth the price and effort."
-----------------------------------------------------------------------
To verify that this is correct just use your own reading glasses. If
you wear bifocals and don't have simple reading glasses just go to you
local chemist or other source of low cost reading glasses and try them
out with the camera. Whatever power marked on the reading glasses that
work best is the power you need. You just need to make sure that the
marked correction is the true correction, or, if buying a Nikon branded
correction lens, that you order your prescription +1.

Thanks for that, Chuck. Have you any idea how to tell from my eye
prescription which lens would suit me? I got my optician to tell me
for my OM correction lenses, but I reckon someone on the List will
have a better idea.

I'm here to improve your knowledge. B&H carries 3 Fuji brand
dioptric correction lenses for the X-Pro1. The price is quite
reasonable at USD 13.95. Leica's equivalents are USD 109. The
Nikons are USD 17.95. Trying to find this stuff is very difficult.
They all tend to use slightly different terminology and a search
that may return the Fuji lenses may miss all of the Nikons.
