I do not know about any issues with Nikon, but I do know that with full frame Canons there can be an issue of some parts of the Takumar lens protruding too deep in the mirror box causing collision of the mirror with the lens. You can damage the mirror that way.
Just to be on the safe side, if you plan to use it on a film or FX Nikon, first check how deep the lens protrudes inside of the body. For DX Nikon there should be no problem. Although I suggest you to do some more research on that since I never tried takumar lens on a Nikon camera.
