i have used panasonic p2hd ajhpx 3000 with cine lens adapter angeniux with ultra prime lens.
then i have trouble about focus. i always have the different from my measuring tape than view finder..this happen in 25 feet to 60 feet above..
when i mesured 26 feet than i check in view finder the object can focus in 60 feet..
i think this is about back fokus in cine lens adapter..

The flange focal depth of the adapter needs to be corrected, it is too long. I'm not familiar with that particular adapter, so I can't comment on the mechanics of how to do it.
