My fucking WB is shit when I shoot at football practices. Plus it doesn't help I am using a nikkor 70-300mm 4.5 non-ED glass. What other recommendation could someone give me? Besides buy a 70-200 2.8 VR..... CP filter? or Haze filter? What ISO setting should I use? I shoot with Auto WB, ISO on Auto, and mostly at 1/500th.
