Default first time using 7d mark ii

I'm shooting a dog agility trial, lots of fast movement.
I'm taking shots in bursts if 3-5
Shooting in mraw
The issue that I'm having is that the camera seems show e to pick up focus or something.
I'll get a few shots of a dog going over a jump, but then the shutter won't work for the next jump
note , this doesn't happen all the time, only occasionally.
Is there a setting I should look at?

I think it's probably a matter of filling the buffer too fast. It surprised me, with dual processor, that the buffer takes So long to clear.

Not the buffer. The shutter button didn't click even when there were 22 shots showing

I'm at school now, don't have the camera with me. However having said that, what is the "bias for release" and what do you mean by "focus priority"?

If you have the 7dmkii camera function set to focus priority it will not fire unless the image is in focus.
Other option are equal priority or release priority.

Try reading page 117 of the manual that came on the disk with it.
To see how to get to the setting screen for this option what the settings actually do.

By default it came with equal priority set, so the camera gives equal weight to firing the shutter and getting the image in focus.

If you are using a slower focusing lens like that Sigma 18-200 or an older non IS version of the 70-200L for fast action, there could be your problem.

The lens I was using was non-IS, but not an older lens. I had a 70-200 f 2.8 L, but I dropped it, breaking it.
I needed a new lens, I was talking to a professional photog friend of mine, he told me that for my type of shooting, IS wouldn't really help. So I got a non IS, $1300 USD vs $2600 USD for IS. I got it probably 1-2 years ago.

I'll look at the other setting and page 117 in the manual when I get home tonight.

You are right, IS is not the issue, what I meant was the older non IS version of the 70-200 focused slower than the new IS V2 version.

Which is a lot more expensive than even the IS V1 version, seems every new generation is getting more expensive.

That priority setting is a compromise though,
the more you move it toward the release priority side the more out of focus images you will get.

thank you for the assistance. I know I should move slower and learn the functions more, but honestly, I got the camera Tuesday and had an agility trial to shoot the following weekend. I have another agility trial coming up this weekend!
This is pretty much all I use the camera for, sure, I take the odd landscapes, etc, but I do primarily dog agility so i'm just trying to learn what I need to do FOR THAT. (I've seen a long thread on another forum about shooting trains, for example. I have no plans to do that...LOL)
