The one thing I always get antsy with on the manual focus end is simply having to focus

All of these shots were not planned and based on the 4000 photos I took with maybe 5-7% of them being decent I think that would shrink to <1% especially with such a quick moving scene in front of me. I guess it comes down to changing technique.
I've noticed in even decently lit situations if I zoom in while editing I still have a noisy photo. I did a bit of searching and it seems that nobody knows exactly what causes it
