A couple of updatesI got my Katz-Eye screen diald in on my K7.
The stock screen comes with a .4mm shim, apparently this is standard, I
foundthat a .2mm shim was the best one.
I tested this with a 50/1.2 lens at f/1.2.
So, if anyone is thinking of installing a Katz Eye into their K7,
probably
don't buy an entire shime set, I expect that if one gets the shims from
.15mm to .3mm (they come in .05mm increments) then you will have one that
will work.
Is your AF in tune with the
manual focusing?
My adjustment method has been to make the manual focus as accurate as
possible via shimming the screen in, and then use the AF bias as needed to
bring the AF into line. The K7 has been very good about not needing a lot of
AF biasing though.
I understand this doesn't matter to some folks who prefer not to touch
the inside of a camera, but to DIY types like myself it's great.
It isn't terribly difficult to change out the screen, and the shims are
actually easier to change out than the screen.
What Katzeye screen do you have? Given your 50mm f/1.2 I assume you
bought it for manual focusing. When the K-8 (or whatever it's called)
is announced I'll decide whether to buy it or pick up a cheap (at that
point) K-7. Either way I'll be buying a Katzeye screen from the onset;
I have too much nice manual-focus glass that doesn't get enough use on
my K10D due to viewfinder woes.
I have the split image with microprism and I had them put the architectural
grid on along with Optibrite treatment.
It makes the camera much more usable for manual focus, the screen is
noticably better than the stock screen (though it isn't by a huge amount),
but having the split image for manual focus is very nice indeed.
One thing I noticed yesterday that I never knew before was how very sharp my
50/1.2 is wide open.
