It was full frame but not infinity hence (I presume) the slight out of focus for the building at the infinity on the lower left second picture .. grr I just now realized that the adapter pass infinity...
(any idea on how to fix that ?( does it need to be thiner or bigger?))

Well, you should actually be able to focus slightly beyond infinity in order to give some allowance e.g. for thermal expansion.
However, if you cannot reach infinity the adapter is actually too long. This can't really be fixed.
