Oh boy, do I disagree with your last sentence...
As is your right.
You'll see I use a 7D and a GoPro, so it's not like I have any direct idea of comparative qualities, strengths and weaknesses or target market or for that matter cost.
When somebody asks a silly question I always think it best to give a really silly answer, as the subtleties of irony can sometimes be lost.
I was a newb once, and I asked a professional video suppliers if they did monochrome tape. The guy said they could order some in along with tartan paint and elbow grease, and in the meantime he could offer me a long stand etc etc etc.
And I still ask silly questions. Sometimes in earnest. Sometimes to poke a viper.
That teacher that told you there was no such thing as a silly question was wrong. There are questions that are sillier than even I could imagine just waiting to be asked.
Thank you for your feedback.
