I know this is a beginner camera, and I am the king of beginners, but how good is the quality on this thing in comparison to more expensive cameras. I've been practicing about 6 months and my buddies say some of my photos look professional, but I don't feel they measure up to the quality of the work I see on the internet. I guess I'm wondering if this camera is capable of professional work. I thought it was a good place to start just in case I decided that photography wasn't my thing... I would at least have a good camera. I'm going to upgrade if I stick with it long enough. What do you gals/guys think?
