D3100 with 50MM lens?

Hey i'm a beginner - will be buying my first dslr.

is it okay if i buy a cheap body of nikon d3100 and a separate 50mm lens. Will the quality be better? And does it have autofocus motor so tht i dun have to use that irritating continuous auto focus? And what other things i will have to buy apart from lens and body?

Added (1). Thanks =-ill buy the G one! And i'm okay wid the 18-55mm but i want autofocus motor - because people say continious auto focus is nt good

There are 4 50mm lenses from nikon- the 50mm f/1.4G and D, and the 50mm f/1.8G and D

the G lenses will autofocus on your D3100, the D lenses require the camera to have an autofocus motor built in (found on models D90 and up)

A 50mm lens as your only lens may not be that great of an idea, however. Its more of a portrait lens, perfect for shallow Depth of Field shots. It is too narrow for normal, everyday usage. The Nikon 18-55mm (kit lens) would be a better choice as a first lens, and then add the 50mm to your collection.

a good prime lens has better quality than a zoom lens, generally speaking.

edit: there's actually 5 50mm lenses- the other one is the 50mm f/1.2, but it is completely manual

English instead of text speak makes your question understandable.

This bit: "And does it have autofocus motor so tht i dun have to use that irritating continuous auto focus." makes no sense whatsoever.

If you want a 50 on your d3100 get the new f1.8 af-s. If you think that as a newbie you'll see much difference between this and the kit lens you're kidding yourself.

It is absolutely great, because 50mm prime lenses will beat any other zoom out there.

Just make sure to buy a G version, like f/1.8G, or it will not auto focus with your D3100 ;)

You just buy a body and the lens, voila.
