Re: Leica M eyepiece diopters

Thanks, Julian. I will call Dave Elwell. I wish I could try some different value diopters before committing to the $80 each. I don't have any local shop that carries Leica products.

Everything I have read refers to the same diopter value in the various M
cameras, up to and including the M6. And I assume it has not changed for
the M7 and MP. I can't explain the differences you perceive in your M's,
but I'll wager it's not related to eyepiece diopter differences. Dave
Elwell in Leica Parts Dept. can confirm (or refute) this, if you give him a
call.

Thanks Julian. This is the exact diopter number that has worked well on my
Minolta SLRs and my Bronica ETRS. So it would seem that it should work on
the Leica Ms too. My original question was "is the old Leica M3 the same
diopter built in as the the M4-P and M5. They seem a bit different to my
eye but not by much.

My understanding is that the M viewfinder has a minus 0.5 diopter built
in.
So, if your aging eyes require a plus 1.0 for clear distant vision, then
you
would want to put a plus 1.5 into your eyepiece.  They do screw into the
existing eyepiece frame, so no "surgery" is necessary.

This has been a subject of some confusion, so you may well get some
opinions
that differ from my own.

Subject: Leica M eyepiece diopters


As my eyes get older along with the rest of me, I have had to add
corrective
diopter lenses to the eyepieces of my other SLR cameras. My Leica Ms seem
to still work fairly well for me though. One thing I have noticed is that
on my two M3's the view is not quite as sharp as on my M4-P and M5. All
cameras have been CLA'd fairly recently so they are quite clean and
bright.
But I am wondering if the diopter value on the M3's may be a bit different
than on the newer version Ms. Also does the corrective diopter eyepiece
from Leica screw onto the old eyepiece or does it replace it completely.
In
either case I need to know what the factor spec is on the aforementioned
Ms
I have. Anyone have the answer here?

Mucho takk,
Dave
