All of the Nikon DSLRs can use the same lenses as the N75, at least to a degree.
Some models won't meter with any non-AF lenses you may have. Also the D40/40x/60/5000 will not AF with the vast bulk of the N75 vintage AF lenses. They require that there be an AF motor in the lens (e.g. AF-S series lenses). AF lenses that use the body motor ("screw driver" drive connector on the back of the lens) will work fine, meter fine, but must be manually focused.
