Which professional camera to get?

Hi okay so I'm looking for a professional camera, we could say. I don't know much, or more like, I don't know anything about cameras. All I have ever had are little digital cameras, but I'm very interested in photography and I have always hated digital cameras. I want a camera that gives me very clear and amazingly defined pictures. I will also be using this camera to take pictures with friends and family and i will most likely take it everywhere so its not like a business kinda thing.

I have no idea which camera to get?
I have heard that Nikon d3000 and Pentac K-x are good options?
I don't know. Please any input will be greatly appreciated.

First things first. Learn more about how a DSLR (digital SLR) camera works.

There's really no reason for you to move up from a point-and-shoot to a Nikon d3000 (or any SLR camera for that matter) if you're not open to learning about using the camera on manual settings. That's really one of the main advantages of this type of cam.

Invest some time in learning about things like shutter speed, f-stop/aperture, depth of field, ISO and lenses (ie. "focal length"). If you like what you read, feel you can begin to understand this info and want to try it out, then you may be ready to opt into a DSLR. If not, just continue with an easier to use point and shoot.

I hope this doesn't sound condescending, because it's not meant to be. Just some good advice for anyone considering the "jump". Hope this helps!

Buy an entry level DSLR. Nikon and Canon make great cameras. Other manufacturers do as well but support via online user forums will be far greater with these two brands. To maximize the ability of your purchase you will want to learn how and why to change settings that affect exposure (shutter speed, aperture, ISO). If you're not wanting to learn how and are going to leave the camera in auto you will be equally served by a point and shoot. A DSLR will not take better photos just because it's a DSLR. There are some small advantages of a DSLR in auto over a point and shoot (less shutter lag for one) but for the money it's not going to be worth it for most users.
I do disagree with a previous post in that you wait to purchase the camera until you learn. I think it is a lot easier to learn when you can practice and experiment as you learn. Buy a field guide for whatever camera you decide to purchase. It will almost always be easier to understand than the user manual that comes with the camera. Get familiar with the controls and menus on your camera. When you're comfortable using the camera and want to learn to take control the single greatest book I can recommend is Understanding Exposure by Bryan Peterson. In simple to understand chapters you will learn what settings you can change and why and how they interact. Read the book and put it into practice with your DSLR and you will begin to fully appreciate the tool you've bought.

Umm I fyou don't know anything about cameras then why the hell are you about to buy a proffesional one? Learn about DSLRs and do some research, then come back and ask the question again.
yes the nikon d3000 (I would go for the d3100) and the pentaX (not pentac) k-x or k-r are all great entry level cameras.

The initial response to this question is that if you're asking this question then a professional camera such as a Canon 1Ds or Nikon D3x would actually be inappropriate for you.

You need a camera that will let you learn about photography, something that gives you room to grow, but also not give you a huge shock. If I were to give you my 5D to use, you would be lost on how to get the most of it.

This is why I'd recommend the intermediate level SLR. Something like a Canon 60D with 15-85mm lens or a Nikon D90 with 18-105mm lens. They will let you learn beyond just the basics.

The D3000 or K-x are both good cameras, however the problem is that they are a little too basic and you'll find that once you've covered toe fundamentals you'll need to upgrade the camera.

I'm assuming you mean an "SLR camera" (not a professional camera).

the Nikon D3000 and the PentaX k *ARE* digital cameras (so if you hate digital cameras then you will want a film camera instead).

clear and amazing pictures have to do with the person taking the pictures, not the camera (the pictures I take with my compact digital camera come out nice and clear with good definition, as long as I do a good job on my end).

Getting an SLR camera (or even a professional camera) will not give you good pictures - only you can do that. You need to learn about good picture-taking habits.
