Don't really know, Don.
My experience is that to avoid having to use the bifocal area of my
glasses I need a +2.0 diopter on the ME Super, but nothing on the MX. So
I would guess that the overall magnification of the MX is a bit higher,
say +1, or +1.5, than that of the ME Super. Seems there is more involved
in viewfinder magnification than just the eyepiece diopter.
Interesting about the opticians. Might check with one of the mail order
surplus optical places --is Edmund Scientific still in business?-- to
see if they could supply an appropriate diopter you could grind down to
size. Also you might look in your yellow pages for "Optical Labortories"
none in Boone but there were a few in Charlotte one of them might be
better equipped to make a custom diopter than your local retail optician.
It is funny how things are so much cheaper (reletive to wages) than they
were in the past, but it is so much harder to find what you need.

I've been meaning to ask this for a while but keep forgetting.
Most of Pentax's film bodies, the ME-Super and MX in particular,
are listed as having -1.0 Diopter eyepieces.
On the MES adding a -3 for my right eye, or a -4 for my left eye
is about perfect.
On the MX a -4 is way too much for my left eye (headache too
much) but a -3 isn't enough for my left eye.
My prescription 'distance' glasses are -4.25 left, and -3.75 right.
1. Does anyone know why the MES and MX are so different
though both are listed as being -1?
2. Am I wrong in thinking what I'm doing should result in -4 or
-5 diopter correction, depending on whether I use the -3 or -4?
3. Does anyone know where I could get custom diopters made?
None of the opticians I've asked can deal with lenses this small.
(About 13mm x 18mm) Actually _none_ of them can deal with
glass lenses at all anymore, just plastic. ;-(
Big TIA
