Any lens, with a maximum aperture of 5.6, is not very useful for sports IMHO. Using such a lens for football under the lights will be near impossible. For football, I use a 400/2.8, in good light I might add a 1.4x TC, AND a 70-200/2.8 on my second camera. As a professional, I shoot from the field. For indoor sports I use a large variety of lenses including the 70-200/2.8 but I also tend to use F1.4 and F1.8 lenses for this purpose. I hope this helps. Best of luck.
Agreed. Can also use a 600 f4. About the only sport that a 200-500 5.6 is good for is baseball, softball, soccer and track provided they are shot in daylight. It is not much use for high school football stadiums at night.
