Little Ravens that have been sitting in my files for a bit

Heard that the Canon EF 75-300mm f/4-5.6 III is notoriously bad, might get an EF-S 55-250mm f/4-5.6 IS. However, these are some of the better photos from yesterday at Sydney Olympic Park

I've noticed the ground in my videos has a slight wavy/pulsating look to it. Do you know what the problem is? I used the Canon EF 75-300mm f/4-5.6 III, but I've heard that it's not the best, and so I'm wondering if I should get a new lens?
