Focal length of lens -EF 70-200mm f/2.8L IS USM zoom
Shutter Speed -shot at 1/640
What is the effect of shooting at this shutter speed? to capture fast movement
Aperture-What is the effect (Depth of field) of shooting at this aperture?f/2.8 is a lower depth of field making less things focused
Position - I would imagine that the photographer is on the sideline close to the end zone, near the pylon.
