I am shooting my son's soccer games under poor outdoor lighting with a Canon 7d Mark ii and the 70-200 f 2.8 I rented. I still had to shoot at ISO 16,000 f 2.8 and was forced to have a shutter speed of 1/250. Would I be better off shooting with a higher megapixel camera (5DS R, 50 megapixels) and a 50 mm lens for example (that is faster, correct?) and then cropping way in? Would that give me less noise and better quality image?
