Every week I get my Sports Illustrated in the mail and can't wait to look at the pictures in the issue. The magazine has absolutely outstanding photography and especially in the fact they are dead-on sharp pictures of players in some sort of motion (i.e. swinging a bat, pitching, etc.). How in the world do these folks get such sharp images during motion? I realize that this is why these guys are pros and I am shooting kids, but I would love to know the secrets.
Are they using center-weighted focusing or something else?
Are they using burst mode or have they just learn the timing of motion?
Would they be using an auto-focus servo mode?
What would be a typical shutter speed for batters and stopping motion? I would use around 1/2000 to do this? Should it be higher or lower?
When a batter is "loading up" for the pitch, where are they focusing on the player to stop they action and especially the money shot of the ball hitting the bat I find that when I am using an auto-focus servo, high burst mode and begin to focus around the belt line and I still can't keep the frame in sharp focus like I would like to.
I have been using my 100-400mm f/4.5-5.6L IS on the field during the games and positioning myself near the dugouts. Should I maybe switch to my 70-200mm f/2.8L IS to open it up and sacrifice the zoom?
Any other advice would be greatly appreciated.
I still have many other areas to work on but man, I would love to know the SI secrets. Thanks in advance.
