hi all, i finally had the opportunity to get out and use my new lens the bigma, ( my shoulder still hurts). i feel i did ok with it with some reasonable still shots, what i would like to ask is, i seemed to struggle freezing the flight shots, (please note i am a complete novice). i tended to use av. awb. 100-400 iso. the problem i think was, i did not get a fast enough shutter speed, how can i rectify this. many thanks
