A pentaprism is the same thing you're used to on your Superprogram, and
ZX-5n. Solid glass for redirecting
the image from the focusing screen to your eye. If you have a ZX-5n
then you alread have a pretty good idea
of the manual focusing with the *ist-D/Ds. Pentamirrors are hollow air
spaces the inner surfaces are mirrored
from my experience they seem to be dimmer overall. A member of the list
has reported that he
thought that the *ist-DL had a brighter viewfinder than the Ds. Usualy
to get equivelent or better brightness in
a pentamirror viewfinder system you lose contrast, which makes manual
focusing more difficult.

Hey Folks,
Thanks for the comments. I have looked at the reviews on dpreview.com, and
saw surprisingly few feature differences between the Ds and the Dl. It
baffles me that such minor differences would merit a new model.
In any event, could someone explain to me the difference between the
pentaprism and the pentamirror? I currently use a ZX-5N, and before that I
used the ME-SuperProgram forever and a day...
Really, I am mostly interested in a good, light-tight box that will accept
my Pentax lenses and let me do my macro in peace. :)
Cheers
Barry
