Shooting football what type of Len

[chuasam]

The fastest 300mm lenses are f2.8. F4 simply requires raising the ISO one step. If you can do it with f2.8, you can do it with f4. I used to shoot baseball from right beside the dugout with a 500mm f4. It worked just fine.

Haha all completely affordable lenses.
If I had to shoot baseball, my biggest challenge would be staying awake.
