Football Tracking All with the 7D:


You may see the same photo with version 2 next to it, which is just a mild crop.


If you take a look at these shots, #4982 the runner was running slow and then he took off, I missed the shot in #4982, so the camera missed the next frame which was #4983 (I was right on the runner, so he must of out ran the sensor [:P])and was a little OOF, but then the 7D locked in again and the next ones were are all good.


In #4987 we have an obstruction (blue jersey #81) and then a soft shot #4988, and then the camera recovers and everything is sharp again.


In #4994 as the players were falling to the ground and the ball handler was being tackled, I was a little slow and the sensor was aimed in between the 2 blue jerseys, but then on the next shot #4995, I was able to lower my aim and hit my target and everything was sharp again.

Here's another example:

The running back takes the handoff and then gets lost behind the blockers #4928 and then he comes out the other side #4929 you could see his hand poking through but white jersey #1 is an obstruction and then the 7D picks him up again in #4930.


Then #4931 is OOF due to an obstruction that comprised 3 frames, so the runner was lost and then #4931 was OOF. A fast or fixed obstruction is usually no problem, however white jersey #1 was running along side the subject as an obstruction for 3 frames. The tracking sensitivity could be tweaked to be slower, but I find that it works in most cases, where I have it which is in the middle.


The 7D recovers in #4932 and then locks focus again and all of the rest of the shot s were good, until the Ref got in my way at the end or his end got in my way.





Here's one more that you could check out if you want. I think these are a little soft, but his determination is not.


I'll tell ya' that this dude was one determined runner, check out his facial expressions!
