So Ive used professional camcorders and other HD cameras before and I received a Canon Rebel T3 last year, so this year I finally scraped together enough money for a new camera. I'm torn between a Rebel T4i, or a Lumix GH3. I've made a good amount of money filming sporting events at my high school, which I would like to take further, meaning, going from just a simple back and forth shot of players, to a professional looking shoot, with a scoreboard on the bottom screen like the ones on ESPN. I am also planning on purchasing a Mac, due to experience with editing on one, and my bitter hate for Windows after my less than pleasurable experience with Windows 8. So does anyone have advice on which programs are better than others, which camera to buy, as well as good lenses for the camera for weddings,outdoor/indoor, and sport photography and video?
