hmmm. I don't know.
I don't have the 6D, but that should not matter for your results. How many lenses have you tried? Did they work with focal on another camera body?
you are fairly straight on with the target, target is flat against a wall/structure, you get the green check when zoomed in live view, have sturdy tripod, floor not vibrating (ie a porch deck), attached usb cable is not jerking the body around during testing, all lenses that have IS it is turned off?
did you try one of their most recent beta builds?
do you have another camera body available to test with your current lenses?
The pro version should let you save a pdf file of your focus results vs. mfa plot. What does it look like?
