I had some focus/tracking issues earlier this year and with football season fast approaching, I'm hoping the Canon community can help me.
In a nutshell, I shot youth lacrosse and baseball and noticed the focus often shifted away from the center AF point, usually to the left. I've attached a couple of photos to illustrate. It might be difficult to make out, but the player to the left is in focus and the player in the center is a soft focus.
Here are the settings I used:
Canon Mark III 1D with 70-200mm f2.8L
Manual (sometimes AV or TV depending on conditions), AI Servo, Rear Button Focus, Center AF point (most of the time) with inner 9 points assist.
C. Fn III (Moved AI Servo Tracking Sensitivity to the left)
C. Fn III (AF priority/Tracking Priority)
C. Fn III (4:1 Continuous AF Track Priority)
C. Fn III (8:2 Enable - Surrounding Assist Point)
C. Fn III (9:1 Inner 9 points)
C. Fn IV (1:3 AE lock/metering + AF Start
C. Fn IV (2:1 AF-ON/AE lock button switch - Enable)
I know with a single AF point and a narrow DOF, there is a good chance that some of my shots won't be spot on. That being said, is there something I should be doing differently?
Should I continue to use the surrounding assist points?
Should I continue to use the Inner 9 points?
What is the advantage of using the Inner 9 versus others?
What would you recommend for shooting football?
Any advice would be greatly appreciated!
Thanks so much,
