Since the pro-sumer label started being tossed around a few years ago, I've always wondered what the difference is between a pro-sumer and a con-fessional camera?

Having sold a lot of gear to both professionals and wanna-be professionals a few decades ago, I've always considered a camera a camera. There are different grades of build between and within brands. The difference for me between a professional and non-professional camera is in who's using it at the moment. I know Nat Geo and other professional photographers who use(d) the lighter, smaller cameras in preference to what are considered top of the line, take-all-accessories bodies because they were better suited to the job, and the job was professional.
