6D and focusing while in live view

Even in Av mode, which I am in about 90% of the time, all I have is the rectangle focus point while in live view and, even though it's pointed at my dog's face and locked on, it still wants to focus way under her face and onto her collar. Is there a trick to getting a decent focus while in live view or am I missing something? I took about 50 shots total and every single one was out of focus inside the focus point... And they were all taken on a tripod, too. Just seems strange to me.

I cant really answer your question, but i was curious why you would shoot your dog in Live View. Why not just shoot with the viewfinder? I would think a moving dog would be a pain to shoot in live view.

f/2.8 is supposed to give you thin dof.

In LV, the focus box is moveable, put it where you want it.

Have you tried 5x and 10x LV?

Shooting live, moving things in LV, doesn't seem like the best of ideas.

To be honest, it really wasn't that bad, but I had my tripod loosened up for some quicker maneuvering. It seems like a cool feature, but not something I would actually use if I was out and about shooting moving subjects.

I understand about the DOF and everything, but if the green box is over her face, even after her standing in frozen sentry mode (as pictured) like she does when the squirrels troll her from the fence, the center of focus shouldn't be about 6 inches behind it. Maybe it's the FlexiZone AF, who knows. But, as mentioned, now that I've tested it out on something that could potentially be moving fast, I can say that it would not be my first choice shooting mode.

But if you used Live view focusing (not temporarily reverting to standard focusing), then you get a pretty large AF rectangle, don't you? Didn't that cover the collar as well?
The collar provides some pieces of good contrast, so I can imagine it's attracting attention from the focusing algorithm.

That's about the only thing I can think of, the collar confusing the camera as her brindle fur blends in with some aspects of the background. At this point I may just be investing too much thought into it.

If you're going to be in LV, just focus manually. $.02.

Not all cameras are created equally for live view. The 6d is using contrast detect, and those areas with high contrast in the focusing point area will probably pull focus. With dual pixel AF that behavior might be a bit different.

For that shot I would move focus somewhere around her left eye.

this thread is regarding video AF but when in live view the camera's focusing system (contrast detect) is the same for video and still shooting.

I think you will see that most everyone is of the opinion that contrast AF is almost unusable except for very specific situations. I have the 6D and just purchased a SL1 for the minor video work that I do. I only use MF on the 6D with video, the little white box is garbage.

I would suggest only using the viewfinder with still shooting of a moving subject (even if they aren't constantly moving), if you have a static scene, with camera on tripod the live view, zooming feature works great.

I've never used AF on a tripod in LiveView. Alway zoom in x10 in Manual.
