I normally only do nature and scenery type stuff, but I was asked by a friend to shoot his soccer tournament. I used a 5D3 with a 70-200 and a 2xiii
I had some problems understanding the case scenario's. Many shots had the background in focus and not the players or was just out of focus. It was a cloudy day, but I could not figure out why my AF was not locking onto what I perceived to be the subject. So I did bit of reading and found this article.
http://www.garyluhm.net/bio/tips_0512.htmlI suppose the major thing where I went wrong is I used AI Focus and Case2. Ai focus is my old habit of not changing the settings on a new shoot from the previous shoot, but Case2 I thought would be good as I do not want to change the AF focus if other players move in front of the lens. Not the case cause the here since the Case indicate you want the background so the players is the obstacle not the subject
I should have used AI Servo and either Case3 or Case5. It seem to better suit moving subjects
I think Case4 is for a very specific shot if the subject is approaching the camera
Understanding this will probably help with the wildlife as well. I will definitely go try it today
