Massive FF issue when MANUAL focussing

Using my z70 last weekend I found that when using the AF the image was always back focussed so I changed to MF and took all the frames using MF, got the prints back today and nearly all the prints are massively FF, as in metres. Used both FA50 and Tamron 28-75 on the camera, neither lens has issues on my DS or K5

Any thoughts? Is there any calibration of the viewfinder I can perform to get it working right again?

some of the viewfinders have diopter correction sliding-swithces
maybe yours need to be calibrated?
do it by using a good lens (I like the 50/1.4) and focusing to infinity (a distant tower or so)

Unfortunately, no diopter on the Z70!

Playing around tonight, AF is placing focus on an object at 1.1m, Focus confirm is at 1m, Apparent Focus is reading 0.8m (all on distance scale of FA50/1.4)

Put a Kinor 135/2.8 on and it is giving focus confirm at the same point it appears focussed in the viewfinder!

The FA50/1.4 autofocuses just fine on my K5
