Configuring your 5D Mark III AF for fast action
« on: February 06, 2014, 01:18:02 AM »
Hi,

a week ago I posted some of my pictures to the birds in flight thread and some people asked me how to configure the 5D3 AF to get these results. Since this is a complex topic I wasn't able to simply respond but I took the time to create an article at dpreview.com. If you own a 5D3 or 1Dx you maybe wanna take a look here:

http://www.dpreview.com/articles/9174241280/configuring-your-5d-mark-iii-af-for-fast-action

If you own a different camera there will maybe also be some useful tips for you. I would be be delighted if you took a look and maybe even left a comment here or over at dpreview.

Have a nice day!

EDIT:
Dpreview did some weird thing to its article section but my original link seems still to be working. However I have recently launched my new website www.focrates.com and you can find an updated version of this article there under: http://www.focrates.com/articles/configuring_your_5d_mark_3_af_for_fast_action/configuring_your_5d_mark_3_af_for_fast_action.html

Hope to see you on my site!
Best Wishes!

Hi cervantes!
First of all thank you very much for your effort and compliments for the really nice pictures.
I couldn't find the time to read concentrated through your article, but the link is already stored
and if I find something to add or comment I will do so right here.

Thanks again.

I don't shoot 5D, but I will most certainly take a very close look to see if there is anything I can make use of on my 7D as I shoot with it. (I bet there are.)

Many thanks for creating such a good article!

Man that is AWESOME! ... excellent and very useful info. Thanks for sharing. Is it possible for you to post it here instead of going through the link? I think a lot members in CR will benefit from it. Once again, a great job of taking the trouble to put it all together. 8)

Wow, thank you all for the positive response!

@DominoDude: I'm sure that there is some useful info for 7D users also. I would personally be interested if the 7D also supports my 2 zone back button / shutter button AF method. Let me please know when you find out!

@Rienzphotoz: I wrote the article over at dpreview because CR is kind of a pain when it comes to incorporating pictures with captions, a hierarchy for headlines etc. I think a link is the best solution.

Great article, especially the undocumented features.  I need to try this but theoretically if you enable orientation linked af point you should also be able to set independent af-on settings for portrait or landscape mode...that is have two selectable zone af points in portrait mode and zone af and 61pt in landscape mode.

Another recommendation is to leave af case mode 1-5 in their default state and use the last case mode 6 for your customized bif settings. 

And you can further customize your use modes by recording your ideal BIF fast action settings to custom mode 3 at the end of the mode dial.  This will let you switch to this mode quickly without looking and will also save all of your customized settings....one may actually want to use different af and af-on settings for shooting a wedding or portraits or even bif with a different lens.

Pretty much the configurability has endless combinations and even more headspinning combos on the 1dx.  Its important to use the settings that work for you and then save them to a custom mode or you may spend a lot of time reconfiguring every time you change shooting environments.

I tried and used orientation linked AF point but the thing is that sometimes you change AF mode setting (e.g. from Zone AF to 61pt AF) in landscape and these changes are then not in effect when you switch to portrait which becomes kind of frustrating and very complicated - so I stopped using it.

And you can further customize your use modes by recording your ideal BIF fast action settings to custom mode 3 at the end of the mode dial.  This will let you switch to this mode quickly without looking and will also save all of your customized settings....one may actually want to use different af and af-on settings for shooting a wedding or portraits or even bif with a different lens.

Yes, that's exactly what I do. C1 is my action mode. You also said to leave AF case 1-5 in their default state and use 6 for BIF settings - a good idea but not even necessary because when you save your settings to C1 and then overwrite AF case 2 while inside C1 mode, case 2 will only be overwritten in C1 mode and not in Av, Tv, M etc!

Thanks for your input!

Nicely done and greatly appreciated.  A lot of food for thought and some insight into the interrelated features of the camera and lens.

@Cervantes: Did you ever try to shoot birds or any kind of sport with AF Expansion mode including 4 or 8 additional surrounding points? I never know which mode is better - Zone or AF Expansion. Can you tell why AF Expension mode would not be appropriate for birds or sports?

Otherwise, very good and informative article!

The single most beneficial aspect of Zone AF is that it will focus on the closest part of the subject.  Even in 61pt you have to get AF using the center point first.  If that happens to be a tail on the far side then AF will track that point and not the head.  There are tradoffs going either way.

Expansion will af on whatever the center is pointed at and the surrounding points will be used to assist AF if the center loses the subject.

The main diff is that Zone will always try to focus on the closest thing in the zones range.
