Doesn't the K7 have a second sensor to overcome front focusing in non-natural lighting? Not sure how well this works though?

Hello I am new to this forum.

I have recently purchased a K7 and I am having issues with the amount of focus correction required on all my lenses (16-50, 60-250, 35, 55). All lenses require large front focus compensation with at least one lens that does not seem to be correctable (60-250) requiring a tad more than -10! Just wondered whether this an issue that any other K7 owners have come across?

Other than the focus issue I think the camera is great.
