Of course if you have a Canon EOS, because that option is not
available. But many Nikon users are using lenses like a 50mm f/1.8
from the 80's or 70's or even earlier because they're so inexpensive
for a very sharp, fast lens. And the older 80-200mm f/2.8 push-pull
zoom lenses are also popular because you get a high quality ED glass
lens for like $400. That's equivalent to the Canon L-series white
lens for 1/4 the price. Only thing missing is the tripod colar.

Actually, they do. Because the D3, Nikon's FX DSLR can use any DX
lens and use the smaller, DX part of the sensor. You just give up
some megapixels. And of course, the Nikon DX cameras can use the
full-frame lenses. Now if you're talking about film cameras, you're
right... a DX lens might not fill the whole film area. Some zoom DX
lenses do fill the full frame at certain zoom ranges but not others.
But you'd be silly to buy a DX lens if you have a film camera. Sure,
it'll work but it would still be silly. And I don't know anyone who's
gone the DSLR route and invested in DX lenses but then wanted to use
those lenses for a film camera because they decided to go back to 35mm
film.

Right. Really cheap ones like the D40 won't autofocus on the older
autofocus lenses. But you can still use them in manual focus. The
rest of the DSLR line will autofocus them because they have the drive
motor. Even the non-cpu lenses can be used with 3d matrix metering
with the D200 (and maybe some others, I only know about the D200
because that's what I have) if you enter the lens parameters. Other
DSLRs can use them but not with the 3d matrix metering.
Really, the only point I'm making is that if you have a decent Nikon
DSLR body (i.e., better than a D40), you have a much wider array of
choices available in the used and older quality lens market than if
you have a Canon DSLR body. And that's only because your Nikon can
use older lenses (20 years or more) that people are getting rid of for
cheap on ebay. Canon doesn't have that option. It's not a huge deal,
but it is something. Especially if you already have invested a lot of
money in lenses from your film days and now want to switch to digital.
