Good job on your first shoot.
In a "mixing" sport like field hockey, soccer, basketball, football, where the players from both team mix it up, I do NOT use zone focusing. I generally use single point AF, so that I (not the camera) selects the subject. * The reason is, in a mixing sport, with all the other players mixing it up right next to each other, the AF just cannot track your subject. The way zone/area or intelligent AF works is different for each mfg, so you must RTFM, to know how it work in YOUR camera, then use it as appropriate for the sport/event you are shooting.
- Nikon's intelligent AF uses color to track the subject, but the uniform of the team is all the same color.
- Canon zone/area focus uses closest subject logic, which in many/most cases is NOT your subject.
This then puts the burden on YOU to track the subject, and not rely on the camera to track the subject.
BTW, I generally do NOT use any of the intelligent or zone focusing, as it often chooses the WRONG subject to focus on. Then I loose the shot because I have to figure out how to get the focus on MY subject. Again, use the appropriate focusing method for the game/event/subject you are shooting. What works for one game/subject may not work for another.
When I shoot action sports, I do not zoom in TIGHT on the subject. I find it difficult to track a moving subject, as they move erratically, if I zoom in tight. Leaving room around the subject makes it easier for ME to track an erratically/fast moving subject. Also a tight zoom makes it harder for me to keep track of a rapidly moving ball.
I will crop as necessary in post.
The more you shoot and practice tracking, the easier it gets. So hang in there.
Tip to practice tracking:
- Go to a large park next to a road.
- Stand a few hundred feet from the road.
- Track the moving car.
- As you are able to maintain track of the car, move closer to the road.
- The apparent speed of the car will increase as you get closer to the road.
The car is a subject moving in a straight line at a constant speed, but it is a good way to get your body used to tracking.
* On the Nikon, I use Dynamic 9 point AF (D9). It primarily uses the selected AF point, but will use the other 8 points immediately around the primary AF point, if the subject moves and I am not able to maintain tracking.
Note: Field Hockey is like lacrosse. You MUST keep track of that ball. And if it is headed your way, you NEED to get out of the way of the ball. If it connects, it could HURT or injure you. If I loose track of the ball, I lower the camera, look around to regain the ball and the play, then set up to shoot again.
