Since we used the peaking function and zoomed in to get the focus I think it could be the back focus. We had an issue with the back focus before.It was after a flight (were the camera was obviously (mis)handeled like any other luggage) even though it was in a Peli case. But then it was detectable in the VF. This time the picture was still in perfect focus. But I’ll try to recreate the last set but with a freshly aligned back focus.
Thanks all for your contribution…
Cheers
