RGF: My lens line up is EF-S 18-55, EF 50f/1.8 and EF 70-200mm/f.2.8 IS ii. (i still have my EF-S 55-250mm but i've been using the 70-200mm instead) so primarily EF lenses. yeah the 1Dx is out of my range
rpt: i didn't consider that yet! hmm...I'm at a point where nearly all my images taken are with the EF 70-200mm f/2.8 IS ii and then sometimes the 50f/1.8 and almost always wide open.. especially when it gets dark. dunno what others lenses i would get.. maybe a faster prime but meh i hardly use the 50f/1.8 anyways at least in comparison to the 70-200mm since I mainly do sports. another thing prolly to mention is that I see this upgrade as a long term thing... like whatever camera i use next, I want to use it until its last clicking shutter before i upgrade.
70D specs look so good for sports photographers!! but surely the catch is the ISO performance. otherwise why the huge price difference?
