Dear experts,

Not me, but I'll answer anyway. :-)

The focusing screen in that D70 was just a matte/Fresnel.
There was no split in the middle where you can focus
by lining up two lines together. And it's hard to tell
in the small viewfinder if the picture is in focus.

Yes, Manual focus is more difficult on most dSLRs. The
full frame ones would be better since the focus screen is
bigger.

There are after-market focus screens available for some
dSLRs. I don't have any personal experience though.

And, in the catalog, there is no diopter (?) correction
for the D70. They have some for other Nikons, but
not the D70.

The D70/D70s and D50 all have viewfinder diopter adjustment.
It's under the left side of the eye cup.
