do you think they would work together? If so thatd be pretty badass. If not oh well it was a nice project anyhow.

The 72 mm filter size refers to the threads in front of the lens.

72 mm telephoto (is there such a thing?) would refer to the focal length of the entire lens unit.

Looking at the products you link, all this information only means that you can use 72 mm filters on any other lens that accepts 72 mm filters. The thing is, that there may be many different manufactures of lenses accpting 72 mm filters. But that does not mean that all of these different lenses will fit the same camera.

The Nikkor 300mm will not fit on your camera. The Hoya filter it's being sold with probably will.
