Actually I've got a Katzeye in my K20D. It's really quite good. The
decision is save $20.00 and get the screen that Nikon used in the FM2 or
get pretty much the same Katzeye screen that I've got in the K20D, well
cut for the K-5II. I really need some advice on FocusingScreens.com.
Those seem to be the two sources for quality screens. Everything else
seems to be pretty much crap.

PJ,
Contact Boris Lieberman.
He has some experience with installing/using the Katzeye.
Yo Boris, oh Boris...

That was the problem, I used the ground glass to get close and then used the
hexagonal in focus indicator for fine focusing, the sensor locked in on that
very sharp twig just in front of the bird. I'm trying to decide right now
between Katzeye or Focusingscreen.com. One uses their own technology, the
other uses the best of Nikon and Canon MF screens, US or Hong Kong, paper or
plastic, 100 bucks with phone support, 80 bucks with email support. I
really do need a focusing screen with decent manual focusing
characteristics, as 3/4 of my lenses are manual focusing primes...

Very nice catch.
I don't think the mirror lenses work with autofocus.
You need a split screen mirror or to use the ground glass.

I believe this is the same Cardinal from "The Victor!", having chased off
his rival. He moved to a different tree. I shot this with my Vivitar
Solid
Cat. 600mm f8.0 hand held at 1/800 sec. It's pretty respectable for a
Mirror Telephoto, the only really noticeable ring Bokeh, visible is from
a
branch quite a bit in front of the bird. While this is a pretty heavy
lens,
it weighs more than the camera, (though not by much), it seems to be
quite
hand holdable with the K-5II. This image is a crop of a bit under 1/3 of
the frame. I could probably make a decent 8x10 inch print from this
file,
thought the branches in front of the bird mean I probably won't.
A couple of other observations, I really need a split image focusing
screen
for manual focus, The K-5II thought something was in focus but the
sharpest
object in the frame was the small branch just in front of the bird. I
don't
know if it's from subject movement or being just a bit out of the limited
DOF from this lens, but the Birds head and eye are not quite sharp enough
in
the full resolution file, though his breast feathers seem to be. The
K-5II
files can take a lot of abuse before they begin to fall apart.
I always thought that the Series 1 Solid Cats were multi coated, but I
noticed that there doesn't seem to be any of the usual coating
reflections
you see even with single and double coated lenses, and no mention of
Vivitar's vmc coating on the lens. Anybody have any information on that?
Well onto the photo.
