Phaseone AF with Aptus 22 info

Hi all,
have the opportunity to buy at a very good price a P1 with Aptus 22 and 80/2.8.
Tried some shots and everything looks working and in good condition (always used in studio).
However, i noticed a little "backlash" when the back is mounted.....it can rotate a little (0.5mm or so).
Is it a normal behaviour?
(always thought this type coupling must be "perfect".... )

Ok, managed to figure it out by myself :)
looks like the hook latch was a bit bended. A small push with the body rear cover fixed the position and now the Aptus feels very solid to the body.
Unfortunately, looks like the AF has a little front focus (about 1cm, i think). I can see from users experience it's not that uncommon. Waiting to test with other lenses, is it a hard fix to do?

a little front focus

ok, managed to fix it.....
Found the af module screws and mechanically adjusted by a little "try and see"......now it looks pretty accurate at close distance and infinity too
