You can go to Nikon's web sight to double check what lenses will work on a
D50, but virtually all AI and newer lenses will "fit' any Nikon DSLR. And
that included older lenses that have been converted to AI. Now, these older
lenses will work, but only in manual mode and will not couple to the meter
or autofocus systems. If you are using an AF lens, make sure the M/A focus
switch is in the A mode. You can see the drive slightly prodruding from the
mount.
According to this, from the Nikon Web site, it should work with all AF
lenses:
High-Quality Nikkor Optics including NEW Compact and Lightweight AF-S DX
Zoom-Nikkor 18-55mm f/3.5-5.6G ED Lens: The new D50 offers seamless
compatibility with Nikon's extensive family of high-performance AF Nikkor
lenses, as well as the expanding family of DX Nikkor lenses, providing
superb color reproduction, razor-sharp image clarity and fast and accurate
autofocus performance.
