EF 70-200mm f/2.8L IS USM zoom

shot at 1/640 f/2.8

the effect of the shutter speed it helped so dat the football players wont look blury cause there wuz alot of movement while he wuz taking that picture.

the depth of the field it helped cause it only focuses on the main thing that he want to come out. so that u can focus more on the football players in the front instead of the back. thats y the palyers on the back are blury while the ones in the front are perfect.

I think the photographer took the picture on the sideline close to the touchdown.
