So you never took photographs in conditions where the autofocus didn't
work precisely enough.

Yes I have. But those situations are in the less-than-1% category.
Fortunately, my vision is not so totally shot yet that I can still
focus with the fine screens that they give you with digital cameras
these days. Maybe it's through years of experience using soft-focus
lenses in the studio or using view cameras. >> Stay informed about: Digital SLR maual focus screens |

Like others have said though, if you have auto focus lenses, you won't find
much need to manually focus with a modern digital SLR. Since your existing
lenses are manually-focused and you want to keep them, you should read this
article before you plan on using them on a modern dSLR. Your new camera
might not even meter properly with those old lenses.
http://www.kenrockwell.com/nikon/nikkor.htm#mfrex.
If you want a modern camera with option focusing screens, Canon offers up
to 11 optional focusing screens for its EOS-1 series cameras. See here for
images of what these screens look like:

Or, if you prefer not to base your decisions on vague, hand-wavy FUD,
just read the facts on your prospective new body.
For instance, I use a Nikkor 85/1.4 AI on a D200 with no loss of
metering.

My very first SLR was a Praktica FX. It was about as completely manual as
they come.
It had a preset lens (nothing auto here). About half of the time, I forgot
to stop the lens down.
The mirror did not return until you wound the shutter.
And, I bought it in 1953.

The high-end Canon DSLRs have interchangeable focusing screens.
The low-end DSLRs don't have interchangeable screens - probably because
their users wouldn't appreciate their usefulness.
I bought a few screens for my EOS620 from a large photographic retailer in
the UK East Midlands and had to explain what they were and why they were
useful (comparing them to interchangeable lenses sort-of helped).

The important thing is, with almost all auto-anything SLRs (digital or
not), ANY of the automatic features can be turned off. Manual exposure
is a given, and you're free to simply ignore the in-viewfinder light
metering if you want to go REALLY old-school. I don't know about Nikon,
but all Canon and Canon-mount AF lenses have a little switch on the side
that turns off the auto-focus.
There's really no sense in getting worked up about finding a camera that
DOESN'T HAVE these additional tools... just make sure the one you choose
lets you work without them if you so desire. As Floyd says, once you
use some of them, you may decide you can't (or don't want to) live
without them... or maybe you will... but either way, they're always
there if the situation demands. >> Stay informed about: Digital SLR maual focus screens |

My first SLR was a sweet little Minolta X-700 with Tamron 70-210 lens.
It had both focus aids - the split-button in the middle, surrounded by a
microprism ring. It was nice having both, as there were always times
when one worked better than the other. >> Stay informed about: Digital SLR maual focus screens |

Correction: they are interchangeable, just not as READILY so as with the
"high-end" cameras. Requires some minor surgery with small tools, but
nothing too extreme.
This guy just adapted the screen from a broken old Miranda dx-3 to a
Canon 300D:

Well, that's about as stupid a thing as I've ever seen. No two camera model's
pentaprisms have the exact same eye-lens to focusing screen distance. Each
focusing screen has a micro-ruled fresnel lens embedded in it to account for the
camera's metering system and optimum visual brightness. How do I know? I used to
make custom focusing screens for my Olympus SLRs. By doing so I was able to
greatly improve on a commercial focusing-screen for microphotography work. My
own design providing nearly 2 stops more of light for viewing and composing.
(The light-metering had to be manually adjusted accordingly for my improved
light throughput.)
Sigh ... more inept morons at the wheel handing out advice on usenet. The parade
role-playing wannabe photographer fools never ends. >> Stay informed about: Digital SLR maual focus screens |

Same here. When I went from film to digital, I didn't think I'd like or
use autofocus. But it's a lot faster than I could ever be, and it
removes one more thing that I have to think about and do. It gives me
more freedom to concentrate on the image. >> Stay informed about: Digital SLR maual focus screens |

Please note that it was Matt Ion who wrote the part about adapting a Miranda
screen for a 300D.
I made the comment about only Canon's high-end DSLR bodies having
interchangeable screens because I believe the original poster didn't want to
do any "surgery" on his DSLR.
