Go outside on a nice day with some clearly defined object that fills most of the frame, ISO 100, f/8 and with the camera on a tripod or resting on something and the timer set take photos using live view and then with centre focus only, One Shot. Compare the images.

I test my gear on birds. Beaks, eyes, head feathers and claw detail tells me what is going on.

Indeed as I hope my photo showed, but as willing a model it was I don't think it would have stood still will I switched from one focus mode to another.
