Hi. Yes it is suitable , in fact , that's the very camera I'm using it on. It rather depends what you mean by 'fully'. The camera will not use any of it's auto features because the lens is totally manual , there is no metering and also the focus aids don't work. However , the camera takes pictures with a tamron lens perfectly well . Set it to 'M' on the dial and then set your own shutter speed and aperture . It will look a little dark through the view-finder ( at least it does on my 135 telephoto lens ) but the pictures come out fine . 

Rotate the white ring can set apertures 

Yes, it is indeed Nikon f mount. 

Any lens that use the M42 size screw in mount. The only other screw mount is M39 and these won’t fit, they would need a different adaptor. They will invariably be vintage lenses and you will only be able to use them in the aperture priority or manual modes, stopping town the iris when metering. Search on EBay for “M42 lens”, that will give you an idea of what you can find.
