This was supposed to be an edit but CanReef does not let me edit my posts...
I guess I shouldn't be so rude and explain my reasoning.
Do you think a $400 camera made to be cheap (relatively),
durable, and easy to use is going to compete with a $2000 camera made solely for high quality photos and video? Additionally, Go Pros and other cameras of its type have the same problem as camera phones. Capable of taking quality HD videos and photos but...they have no zoom and true macro capability which makes them limited in what they can do. I just think you are putting Go-Pro onto a pedestal on which it does not deserve to be on. They are definitely solid cameras, but like Apple products, too expensive for what you are paying for because they are a big brand
Additionally, the OP has mentioned that he is actually a SHE and that she wants to pursue macro photography. DLSR is the only way (at least easily) to get quality macro images and get super-macro shots.
Also, check out that guys videos. He does some AMAZING videography.
