The
only thing that really fits together between these bodies are the
outer
dimensions of their screens.
Both
cameras have a total different finder system that demands a
total
different screen, and they have got it !!
Put
a SA-26 (LX-screen especially designed for long tele-lenses) in the LX
with
a 4/200 and it will help you (a bit) against dark corners in the viewfinder.
Now
put it in the MX. Shock!!
Where is the light!? Only a spot in the middle,
the
rest is deep darkness.
Now
a SA-21 (for general photography) and a SA-1(same MX-type)
both
in MX-bodies
(for
example with 4/100 macro lenses).
Compared
with a SA-1 the SA21 might be that "famous-forum-1/3-f-stop" brighter,
but
the grain is horribly precise to see, whereas
in the MX with its own screen
the
grain does not jump in your eye so sharp,
black and brutal, that with wideangle-
lenses
it even covers the fine structures in your picture.
And
don't let's forget, that we sometimes have more darkness in the corners
when
using LX-screens.
We
don't need more examples, we don't need normal LX-screens, and we don't
need
(sorry, if you have already bought one) LX-2000-screens.
I'm
sure type
60
is
better than the old 20,
because that never was so good,
whereas
other brands (Minolta, Hasselblad, Leica,...) already had
high-tech-inventions
in their viewfinders many years ago.
But
with the finer grain the MX-user would also get an
under-exposure
of
nearly 1,5 EV.
And
to make confusion perfect, nearly every single type of LX-screen will give
us
an
un-expected metering result, no matter whether it's an old or new type:
SE60=1,5EV
/ SE20=1,5EV / SA26=1,5EV / SA21=0,5EV . . .
Nobody
who has really tested 5 or more LX-screens in a MX,
will
continue to talk about the
"small
amount of under-exposure you can ignore".
Which
MX-User will really be delighted, to adjust his exposure metering
whenever
he has changed the screen?
As
I mentioned above, both cameras have total different viewfinder systems.
Look
through a MX and a LX with a standard lens. One could think there is a
short
tele
on the MX! Why? Because the MX has a much
greater finder-magnification!!
The
next big difference you know very well: Little MX
has a very small prism-glass!!
Third:
Different
optical distances from eye to viewer-image!!
Now,
who could await, that under these circumstances LX-screens would work
properly
( or even better !!! ) in a MX, whose findersystem
demands
total
different fresnell-lines on the screens.
What
we need (and I'm glad to have it)
is a screen of new technology,
that
is made for a camera very similar to the MX
(no, it's not the OM-1),
with
exact the same focus distance.
Do
we want it much brighter? Letting pass much more light?
No!
So
nobody has to throw his MX-screens away
(after
all we've found them working even better than those LX-ones).
The
new
high-tech-screen has to bring a
bitmore light in the corners of our
MX-viewfinder,
and we want a
finegrain,
that is nearly unremarkable.
The
result is that bright
and
clear
"panorama"-image, that many
MX-fans
are longing for from the first day on.
That's
the Hitecscreen.
The
only problem to solve, is to fit it into the MX screen-frame,
because
of its larger area.
I
will do this risky cutting work for you professionally, and of course leave
a
little "tongue" to grip the screen with the tweezers of the MX or LX screen-case
(if
you don't have these tweezers, I will send you one I made by myself).
Naturally
it is good "old" japanese technology
and not one of those
american
wonder-screens, that were sold from different USA-companies
for
huge amounts of money, until finally the growing communication in the web
brought
together all those, who had bought one and made bad experiences.
