Here are a few of my favorite photos of the Kansas State University Pride of Wildcat Land Marching Band from October 29, 2011 in Manhattan, Kan. The first seven images were taken with a Canon 400/f2.8 lens on a 1dMk2 body and none of them have been cropped. The remaining six images were taken with a 15/f2.8 lens on the same body.
Thanks for looking.
A lens like the 400/f2.8 allows me to capture images of just about any musician on the field.
