Hi Dave,
You already received many suggestions and possible cause of this issue.
My proposal is to exclude some of them. To do this can you please make test image in more LAB environment?
E.g. shoot flat peace of newspaper with controlled light condition – use different focal length and aperture, For calibration you can use old trusty lens with similar focal length.
Other interesting lab test is AF accuracy at different AF points.

Miro
