What lenses are compatible with my Nikon D90?

I've Recently Bought a d90. I'm a little confused with what is compatible with it. I've come from an Olympus E-30 so I'm a newbie to the Nikkor range. I'm looking into a wide angle Lens and a Macro. Does anyone have any suggestions on a decent lens for each for cheap-ish?

All Nikkor lenses are compatible with all Nikon cameras. They all have the same "F-Mount" and are all interchangeable.

For wide angle I'd go for the 18-55mm

I don't know about a macro that would work for you, as there aren't really any that are cheap. I'd suggest looking at lenses made by Sigma, you can get them with F-Mount, and they're generally cheaper than Nikkors.

I'd also suggest that you get the Nikkor 50mm f1.8 prime lense. It's just over $100 & it's a fantastic all around lens.

Anything Nikon AF is fully compatible.

Wide… Sigma 10-20, tokina 12-24 or 11-16 f2.8 come to mind

Macro, I'm really, really fond of my Tokina 100mm f2.8 but, all 3rd party macro lenses are optically solid at good prices.
