How to use an olympus lens on a nikon camera?

I have several very old olympus lenses, and a Nikon D70 camera. Is there an adapter that i can buy that would allow me to use my lenses on my nikon D70?

Usually such a thing is not worth the hassle.

I don't specifically know if there are adapters to mount Olympus lenses on Nikon cameras, but usually you lose a stop or even more of maximum aperture, you lose autofocus and most likely also light metering. It really isn't fun to use these lenses then anymore.

You'd be best off if you sell them and buy compatible lenses instead.
