->> I am having focusing problems with my Al Servo mode. Has anyone set their CF. 20 to setting 2 (moderately slow) or 1 (slow) and what results have you gotten? |

->> Robert,
When using the Al Servo mode with my Mark II, while shooting basketball games, my 70-200mm f/2.8 IS USM lens has "hunt for focus" issues. |

->> Plug your camera into your computer and turn on Personal Function 14. That disables the "hunt for focus". |

->> I recently set mine to slow for most things and it has helped quite a bit. |

->> I take my 70-200 f2.8 off the minimum-to-infinity focus setting and that helps a good bit. I find that my "N" doesn't hunt nearly as much as my older MKII. |

->> Setting Cf 20 to slow or moderately slow won't help with hunting. Well actually it might, if hunting is caused by someone running between player you are shooting and your lens, but otherwise it won't help with your problem. Cf 20 switches speed or better time left for af to switch to new object which came between lens and original object. I keep it on slow, since usually those things which come between are not something I want to focus on, so focus stayes longer on original subject.
As far as Pf 14 goes, personally I don't really like it. To many times I get feeling something is not working, since there's no af movement :) But I agree that it can be usefull. |
