Best Nikon camera 2012? Recommendations please?

I want a new professional camera, with the best features, but I don't know which one to get.

Do they have waterproof too? How can you make a camera waterproof?

You obviously don't understand what a professional camera is. The D4 will be on store shelves in a few months for a modest 6 grand.

If you want a pro camera just because its a "Pro" camera don't get it. I learned the hard way a few years ago. Most people think of a pro camera as what is referred to a DSLR camera and some are actually user friendly for people that has almost no experience with SLRS

Bottom line if you want a "Pro" (DSLR) heres what you should got
If your experienced Low budget - Nikon D2H Medium budget- Nikon 300/300s High- Nikon d3/d4 (D4 looks sick)

Entry level - I would say d300, 3100, 5000, 5100 are the nice new ones d60 70 are sorta entry but preatty obsolete

Kinda medium range - D90 D80 and if you know a good amount D7000

The new flagship d4

Go for Nikon D3100 camera is built for the beginner to moderate photographer. The camera is light weight compared to other Nikon DSLR's, while at the same time providing the Nikon signature lens and operating system. The only problem I had was when you want to tak action shots, compared to some of the other models (D80) it does have a slight delay, and it also requires a corded remote. Other than that it is a great investment!
