So I'm not a professional. I dont make any money from my photography. Its a hobby for me and my wife. I make money from my primary profession and spend it on gear i have no right to by. :)
That being said, I currently have as my primary body a d300, but I still use my prior body a d2h as my backup. Its not nearly as good, of course, but depending what Im shooting, and if theres enough light, I can still get good photos from it. Im thinking of upgrading to either a d700 or d800 (d700 probably). But here's the thing... im not planning to get rid of my d300. I couldnt get much money for it. But I always hear about people selling their bodies. While part of me gets it, part of me is honestly confused. Is the amount you get really worth selling a body? why not have a backup? Or a second shot if it can be controlled wirelessly (or another photographer)
Im honestly curious. Even as a hobby photographer, i like having backup cameras.
