Nikon Lens Mounts

[Kurt]

What's the difference between a Nikon D mount and F mount lens? I was looking through Nikon's digital offerings and they have model D100 that say's it has an F mount and a D1H that says it has an D mount. Are either of these compatible with older (film) Nikor AF mounts?

Hi Kurt;
one good thing about Nikon SLRs is that they share the same mount, the F mount. This means that you can use manual focus lenses on autofocus bodies and viceversa, (the exeption being the very early lenses, but they can be modified by a specialist).
"D" is just the name given to some autofocus lenses that have a chip which measures the distance the lens has focused on to calculate the flash output, (so this is only usefull for flash photography). Newer autofocus lenses also have this chip but they are no longer named D.
Manual focus lenses can be used on the latest bodies (film & digital) but the camera will only meter on manual mode. To get the full advantage of the camera's metering modes you can have these lenses chipped. This, I guess, is what Nikon means by "D-spec manual focus lenses".

Looking at the specs of the D-100 they list the following type lenses that are compatable:

-D Type/G Type AF Nikor - All functions
-D Type Manual focus Nikor - All functions except auto focus.
-AF Nikor other that D or G Type - All functions except 3D Matix Metering

Ok so two lenses I have how do I know what they have (both Nikon mounts)
-Nikor 50mm Manual focus
-Tokina AF 27-70mm
