im pretty sure your better off getting more lenses first, espeiclally since your still on the kit lens, which suggests there isnt a need for a body upgrade at the moment
I would suggest getting better glass first. How long have you had the D40? Rather than upgrade to the D80 you might as well save up and then get a D200 or save up a little more and get a D300. Personally I see no benefit in upgrading to a D80 from a D40. Its not sa big enough upgrade to justify.
YES! Get lenses first. I have both a D40 and a D80 and honestly believe that the D40 is the better of the two cameras, so forget that idea. For macro, just get any used macro lens and manually focus. Manual focusing is the norm for macro work anyways. You can get used 55-60mm macro lenses for $200-300. For a "zoom" (I take it you mean a telephoto zoom) the 55-200VR is great for around $200-250, or the older non-VR version for $100-150.
Yes, I'd go for lens too. Also there is heavy speculation that the successor to the D80 will be coming out soon. So if you're aiming for that model, may aswell get the new one. cheers, david
