Can I used my old Nikon film lenses with a new Nikon digital camera?

How old they are is important. The answer is that any lens made to the AI specification or later (1977 on) can be mounted on the digital bodies unless it is one of the relatively rare F3AF lenses. The extent to which modern lens or camera functions work will then vary with lens/body combinations.

There are then oddities. The D40/D40x is the only digital body that can mount the earlier Nikkor pre-AI lenses made between 1959 and 1977, but not the F3AF lenses. It is compatible with the widest range of Nikkor lenses, but does not provide any exposure metering with the manual focus lenses. (The F4 is the only body that can accept the whole range of Nikkor lenses from 1959 on, including the latest G and VR specs lenses. VR lenses will auto-focus on F4, but the body does not support the VR itself.)

Without knowing more about what lenses you have and what digital bodies you might be contemplating, it is difficult to be more precise. I have included a link to the Nikonians site which has a table with the details. Similar information is available from Nikon if you search their knowledge base in the support area, it is just more difficult to find.
