Strange image shake on R7

Sorry to be off topic a bit but there are a mounting number of R7 AF issues threads. I'm still experimenting but there are a lot of variables that I can't get my head round. LIke today, to pass the time whilst a car passenger I turned off servo to single shot, turned off subject tracking, subject recognition and eye recognition. Put it on single point focus. Pointed it at the number plate ahead of the car going at about the same speed as us. Pointed and got white square over the number plate then pressed bbf to focus and it jumped with about 7 red squares straight to the centre reservation rails !!

That sounds like you had BBF set to engage other settings. If you are in one shot (not servo), no tracking and no eye detect, and using single spot (either small or big), the focus will stay inside that spot. I've just tried it with mine, and I can't induce it to focus on anything outside of the spot. If you're in one of the zone modes, you will see the multiple focus squares inside that zone (it has to pick something to focus on inside the zone), but nothing outside the zone. You should check your custom settings to see what you had the BBF button set to. This isn't a problem with the camera, but with your settings. Or, it might be that you have a faulty camera, but what you are describing doesn't happen with a non-broken R7, unless you had programmed the back button to use other settings. If that's the case, it doesn't matter that you turned off the other settings.

I can't find a way of covering something I want to shoot and it permanently staying there.

What I have done is program my AF-ON button to use the "register/recall" settings, and set it to single spot (small) with no eye AF and no subject tracking. That forces the camera to focus just on what's under that spot (I can use it with one-shot or servo). It stays there. It works perfectly. I don't use it often, because I find the subject and eye-detect and tracking of the R7 to be superb. But occasionally I need to force the camera to focus on a particular thing, and that's a quick and easy way to do it.

What is going on?

It really sounds like a problem with your settings. You might want to reset everything and start over.

Then back on site and with the preferred settings from "Ron's" Whistling Straits video tried to get an owl not too far away flying slowly, against the sky. Seemed to get red squares over owl but on viewing not in focus and no focus points showing at all . Then a few seconds later against a fairly distant grass background it managed to focus on about three out of five in the burst.

Probably need a new thread.
