Hi all,
What's the way to go with focusing, which usually gives the better results ? Auto or manual
 
Depends what you're doing. Action stuff autofocus usually, landscapes manual, macro manual, varies really.
 
LOL...This can cause as big an argument as RAWvsJPG.

Some say, manual for action, presetting your focus on a specific part of the track, pan into it and capture at the correct point.

Me, I'm autofocus with Dod.

Also, I use Centre Point only for action.

What are you specifically asking about? Sports, Portrait, Landscape etc.

Carl.
 
I mostly use AF all the time. The main thing is to decide which or how many AF points to enable and which focusing mode - Single or Servo

The 20D has an additional focusing mode called AI Focus. The system tries to evaluate speed and direction of travel and anticipate where the subject is going. This mode is best ignored completely. :D

Mostly landscape just trying to get everything pin sharp
 
I usually use AFocus same as CT. For everything bar macro
I've never used AIFocus with results... it usuall dont

Macro - you have to use manual focus.

.. or if its too dark and the thing hunts...
 
Doug, the best thing you can do is learn about Depth of Field & Hyperfocal Distance. They are more critical for landscape work than the actual point where you focus.
 
I agree with Richard. In a nutshell, focus about 1/3 of the way into your landscape and you will get max dof. (ish!)

But doing it properly it would help to have the lenses with the aperture marks on..then you can line up the aperture you are using with the infinity mark etc and then look at the other mark of the aperture you are using and it tells you how many feet/meters away you need to focus.

Sounds difficult but isnt!!
