Yes. And that is an AMAZING lens, by the way.
The Nikon 50MM can be purchased online as well as in stores. Amazon and eBay carry the 50MM as well as the Nikon store itself (online and in stores). A store such as Best Buy or another electronic store will sell the Nikon 50MM as well.

Yes! Manual focussing is easy and that is a great lens.
All lenses with Nikon mount are compatible with Nikon D40. If the question rephrase : "What lenses are able to autofocus with Nikon D40", then the answer is : the new Nikon AF-S lenses (with Silent Wave Motor inside), Sigma lens bearing HSM code, and upcoming Tamron lenses (18-200mm, 17-50mm and 70-300mm).
Approximately $270 with 50mm f2 lens.
Being that the obj.is 50mm,I would put on a pair of 1in.high rings.
There are many good Nikon lens for portrait photography. However, perhaps the best Nikon lens for this purpose is the Nikkor AF-S 50mm f/1.4G lens. The cost of this lens is approximately $450.00.
For ~$100.00: the 50mm 1.8. Hands down best low light performance / cost ratio.
With few exceptions, you're going to be much better off only buying Nikkor lenses. Stay away from Sigma and Tamron. The D5000 doesn't have a focus motor, so only buy lenses AF-S, AF-I, or G lenses if you want auto focus. I'll assume you already have the mediocre kit lens (18-55mm). Next you should invest in a fast prime. The Nikkor 35mm f/1.8G AF-S or the Nikkor 50mm f/1.8G AF-S are both excellent lenses.
It depends on what your using it for, if you want something cheap I would go with a 18 to 55 or a 50mm prime.
It is: 50mm = 5cm
