Does a Sony NEX-5 camera good for taking professional photographs?

I am looking for a professional DSLR camera that produces high quality raw photographs. I want to click photographs outdoor as well as indoor, portraits, de-focused backgrounds, medium zoom photographs and macros as well. I reviewed few cameras and I found SONY NEX-5 admirable as it fits my budget and due to its compact design, hence useful for easy handling and carrying. Please give your opinions or suggestions.
