I need help with making a educated decision on my next camera. I currently have a canon T2i and use it for taking pictures of my daughters all star cheerleading team. These events are inside and the action is fast in usually dark arenas. I recently bought L 70-200 2.8 IS II. This lens takes outstanding pics on my beginner camera. I am looking no to upgrading camera and have been waiting on the 7dii. Should I wait or on this camera to maybe released some day or look into another camera.
