Shooting moving kids with 6d

I'm having the same issues with the 85L out doors. The outer points just focus lock and then miss. Went back to single shot for the confirmation, and might change AF back to shutter button to fire immediately on lock to see if that solves anything. I'm missing more than I'm landing at this point.

I understand that DOF is thin, but I'm giving myself good working distance and still missing.

Glad that I am not alone. Seems just like my case, camera said AF locked, and when you look at the shot, nothing is in focus. It is not MA issue, there doesn't seem to be anything in focus.

yep, had my daughter do some posed shots, and a crapload of totally missed shots...............

I really feel for you guys....

I'd just stick to center point if I was you. The outer points are like gambling, you lose more than you win I'm afraid...

Interesting to see that the outer points fail when you are shooting at large apertures (F/1.2 up to about F/2.8) when the subject is moving and the distance to the subject is relatively small.

Read Charlie's post again.

He got his daughter to do some posed shot, meaning static and stationary and it's still fall.

Non crosstype points is simply hopeless period.

I know very well as I used to shoot with a 5D2.

Well, I had a 5D3 vs 6D thread which got closed, so I'm still reading all those 5D3 and 6D threads (also going to add the 70D and 7D2 once they're out). The outer points on my 550D are also not very reliable (non-crosstype) and I have a weak spot for the 5D3 AF system. So therefore I find it interesting to see that, regarding the outer points, there isn't much of a difference between my 550D and the 6D.

I am still hoping more 6d users chime in. So far only three (me, Charlie and mavgirl) having 6d and two out of those 3 are having the issues being listed. Sorry if I missed counting some other 6d user who posted in this thread.

I'd like to see more as well. I'm well aware of the fact that just because I'm doing well with what I've got doesn't mean I won't run into a lens that gives me the same kinds of issues that you guys are having. I've seen 85's mentioned a couple of times. I use the Samyang 85 which takes the AF issues out of the equation for me. I do wonder if I'd see more AF problems if I picked up the 85 L.

I have a 6D and shooting at 1.2 with focus lock and/or BBF is a disaster. There just isn't time to do anything before you or the subject moves out of the DOF zone. It helps to pretend that you are capturing kids at a skate park @ 300mm - with no IS.

Here are 250 shots at 1.2 (50L) with a 6D:

All shot on full servo + continuous drive. I was doing great until the second set, when I didn't notice the SS drop below 1/120. I've got minimum set for next time.

Question is were you using center point only or outer points, or a combination of both?

And how would you rate the outer points as compared to the center in terms of speed and accuracy?

Same questions as Kin2Son, whether you using center point or outer points and how do they compare in your opinion when shooting at wider apertures.

BTW - The issue we discussing is not DOF, at least not in my case. When I getting OOF shot, everything in the frame is OOF. Doesn't happen all the time but it does happen. With subject relatively still (kids), I fire multipel shots, some are good, some are OOF as I shown above. And this happens when using outer AF points. And camera did AF confirm.

I usually use my 7D for baseball, but really like the combination of the 6D and 135L (especially for evening games). I only use center AF. I use BBF.

From today. Single shot mode, top center outer point.
Totally Off, doesn't know why camera thinking there is focus lock.
all rest nailed it.
If I consistently get something like this then I can live with it.

I rented a 6D for 5 days last December and with action shots of my dogs in AIServo or using the off center focus points or all points my 40D did about as well, and in a few situations better. But if I were using center point focus the 6D was very superior to the 40D -- but I really wanted an improved focus system over my 40D for those moving shots. I've preordered a 70D and am waiting for reviews on that.

I do have a question -- I didn't get to properly "play" with some of the 6D focus options that the 40D lacks -- since focus is so critical in these shots, have you tried playing with the Tracking Sensitivity, Acceleration tracking, and use AIServo with image priority set to "focus priority"? I wonder if any of those settings could help the 6D lock better in those situations. I don't know as I didn't have time to try all of that out --

I suppose you guys need to see my 100% keepers with moving kids. I'll post up later. Evidently you guys aren't adjusting the AF options in the custom menu.
