First time to post here. I've started taking pictures of indoor sports and I will be getting a new camera and lens for my birthday in July. I take pictures of my friends hockey games and roller derby bouts(in a dim light skating rink) I've been taking pictures with a Canon ELPH 520 HS(not a camera used for sports but the shots that have come out good are pretty good for a point and shoot camera). I'm close to the action already and can move about so I don't need a mega-zoom camera and lens. I'm allowed to use flash(amazingly though, the roller derby pictures have come out brighter and better without the flash then with the flash, even in a low light rink). I only post the pictures on Facebook but I still would like quality shots. I've narrowed my choices down to a Canon T2i(or T3), Nikon D3100(or D5100) or a Panasonic FZ200. If I get a Canon I'm either getting the 50mm/f1.8 lens or the 85mm/f1.8 lens. Which camera and lens do you all suggest I get? Any advice and recommendations are greatly appreciated!
