Was just wondering what everyone uses for shooting moving targets - car, aircraft etc... with. I usually use Manual Select with AF point extension but was wondering if this is the best or is it better to use another of the AF modes to get sharper images ?
I used my 7D with expanded points and used the zone AF, where if you moved the point, it would highlight the zone (center group, left group, right group, top group, bottom group, etc). That's good for large objects that fill your view finder. But I also found it would grab anything under those AF points in the zones when activated. So I slowly moved to single point, manual selection, no expansion, with AI Servo set to low sensitivity, and the tracking I get now is far more accurate, and I get a lock and it stays locked.
There's more to a sharp image however. You could have focus, but have a blurry image due to slow shutter and no stability giving you vibration/shake blur. You'd have to post an example where you think it's not hitting the target.
