1d mkiv ai servo tracking

Just curious on what you guys or ladies, set your ai servo tracking speed to and do you change it or just leave it alone?

It depends on what you shoot, your technique, the position of the Sun relative to Mars and how many days are in the month. (The last 2 might not be entirely accurate )


From previous experience with the 1DMKIIN and to a lesser extent the 7D, i took the MKIV out of the box and immediately set it one notch up from Slow. This has always worked for me for Motorsports, Football (as played mostly with the feet) Rugby, Aircraft and anything that moves relatively quickly.

Remember it's the tracking sensitivity you're actually setting and not the speed.

It's important to understand that this setting does not control how fast the servo will track a subject. It controls how quickly the AF will jump from one subject to another when the focus distance abruptly changes. So if you are tracking an athelete an happen to allow the AF point to wander off of them for a moment:
1) In 'slow' the AF will stay at the same distance and wait to see if you pick up the athlete again. After a second, it will jump to be background.
2) In 'fast' the AF will immediately jump to the background.

I tend to use 'slow' or 'very slow' because of my personal way of shooting action. I always re-press the shutter button when I am changing subjects while shooting. For this reason, the 'fast' setting has zero advantage to me because I never want the AF to change subjects.

The fast setting is if you may have new action develop in front of the current subject and if you would want the camera to automatically jump to that new subject.

Thanks both of you for the info, I had a general idea of what you both said however this helped. I normally don't shoot suer fast subjects, some wildlife, some portraits and some landscape. I will be shooting the airshow next month, so in that case it sounds like it may be adventagous to set it a little faster, right? Right now I have it on default neutral setting. The focusing system is so good, but also kinda complex so I am still learning the in's and outs. It makes you not want to touch anything besides another 1d, that's for sure.

Based on what you're saying here, I'm not sure you understand yet what the setting does. Here's another for instance: the other night I was shooting somewhat back from the sidelines of a football game. If a coach or someone walked between my position and the players I was focused on the field, the camera would want to try to focus on the coach. If the setting is "fast", the camera jumps immediately to the coach. If the setting is "slow", it remained focused in the background on the player for a lingering instant, then it would acquire the coach. So, with it set to slow, when I saw the coach enter the frame, I simply lifted my finger off the button until he passed out of the frame, and that way I never lost focus on the play. Make sense ?

Yeah it does, I did misunderstand. I thought it tracked from on point to another, for example if a jet goes left to right across the frame I thought it would move from point to another and the speed was how quickly each point acquired the jet.

I generally lower it to one notch above Slow. If find that combined with CF. III-4, I can usually track what I need.

You "really" need to do the tutorials on your focus system and learn it, otherwise you've wasted $5000 and will not be happy with your results.

some great info, i watched a few of the tutorials. some info I knew, a lot i didn't. Now i am going to have to really think about using the back button for focusing and exposure.
