How much can nikon professional cameras cost?

My friend has taken up photography and i want to too. How much would one of those professional cameras cost? Like the model d90 and other ones like that? Thanks! And i'm not looking for a plain digital camera. I want one that you can like manually focus and stuff that is easy to use

The camera you're looking for is called a DSLR, which is a Digital Single-Lens Reflex.
Nikon's website lists their own prices, and on Nikon's website the D90 is listed for $899.95 without tax. Tax will probably raise you $50-100. At best buy, the D90 is listed for $1, 199.99 without tax. I live in New Orleans, and there are plenty of camera shops in my area, you should probably research the camera you want, and then look for camera shops in your area. DLRS go on sale at best buy, and you can find some really amazing package deals saving you at least $100 on a bundle. Also, if you were to buy a camera from a camera shop, I know in New Orleans there are some great deals, it just depends on the merchant, and the time of year, etc.

Nikon Professional camera range starting from $1000 - $12000. Search online at Nikon website. There's option for photography, if you don't want to buy, hire a camera on rent on monthly basis.

There's a trusted website with DSLR's. Nikon is a great brand but before buying into a camera system, Canon should be looked at as well.

Nikon D90 is not a pro-camera! Get a used Nikon D200 (ebay)!
