Fair enough, that's better quality than you get from a $200 camera. You or somebody else may regard it a professional camera and I suppose that's fine, in a sense. However, I am highly doubtful that it is, in fact, a camera that is, by the manufacturer, aimed at professional users. I am also highly doubtful that dedicated photo stores would market it as a professional camera.
I currently own a Nikon D7000, worth $1100 in the US (that's without a lens) and that's designed and marketed as amateur/enthusiast. When it comes to Nikon, and with the arguable exception of the D300s (some professionals simply need the APS-c 1.5x factor), you don't reach cameras designed and marketed as "professional" before the D800, which is $3000 in the US (also without a lens). Other brands tell a very similar story.
I took the following, unedited picture with a four year old Nikon D60 which, even when it was new, was designed and marketed as an entry level amateur-camera. It cost $740 (
with a lens and small, external flash included) here in Sweden, and do note that Sweden has high taxes.

Whilst it's true that the lens, a 50/1,4, is techically regarded professional, it's an old model, one of the absolute cheapest professional lenses and its strongest selling point has been beaten by the non-professional, even cheaper 50/1,8G.
What I'm trying to say isn't that money == quality (although I understand that it might be easy to think that's what I believe, based on this reply). What I'm trying to say is that you have to go very, very far up to find cameras that are actually designed and marketed as professional and
those are the only cameras that I, personally, refer to when speaking about professional equipment.
If the camera that took your photo is a Nikon D3100, Canon 1100D, Pentax K-x or Sony A37, then fair enough, they're good cameras capable of very good image quality, even better than in your photo, not trying to bash but it's simple fact. It's just that I will not agree that any of them are professional, and neither is the camera that took your image, unless the photo isn't a fair represention of the camera's potential. You do get A LOT of bang for your buck these days, even great quality doesn't require professional equipment.
