EOS 7D Mark II not focusing with Tamron and Tokina lenses

Canon 7D MK2

Two holidays last year were 'ruined' by the results of my photos.

Used centre-weighted setting but with a couple of lenses the camera was obviously struggling to focus; one was a Tamron 70-20 and the other a Tokina AT-X 28-70. I've had Tamron check for faults with an inspection and test - they found no fault. I took some photos where the focus point in the viewfinder was just a single square in the centre; I think that these photos are the ones that were pretty awful, with no focus to speak of.

Any advice?

Thanks.

... and again, thanks for the help.

Here is very brief overview of the 7D Mark II camera body.  He briefly discusses metering.  The entire runtime of the video is about 31 minutes.  Most of his videos of this are about 90 minutes.

The camera performed exactly is it has in the past!

Did a factory reset and looked at what the default the factory settings are. Whatever I'd done, that fixed it. Had a few duff shots but that's obviously down to me - I do have a tendency towards complacency, when I should be taking more notice.

Anyway, thanks again for your patience and suggestions, as well as the links.
