Hi Tony
The focus was easily corrected by using a focus chard downloaded from the internet. One was for actual focus vs focal length and the other was to check forward/backward focusing issues, this requires a fair bit of faffing about but looking on Youtube there are plenty of instructional videos on how to make the necessary changes in the camera..
My main issue was both lenses needed adjustment in the camera, this was very noticeable with wide angle shots where the outer 2/3rds were blurred due to the focusng issues.After adjustments the results were exactly on the money compared to my previous camera.
