So I have a Nikon D3000. I'm was looking around at old lenses that are cheap to fill in until I can get a new Nikon lens. Anyway, I came across this and wondered if it would fit or what adapter I would need to make it fit. I know it says at the bottom but I don't really understand it (don't laugh). I only want it because it is a cheap 200mm lens and should hopefully last until I can afford a new lens.
