Ursa Mini Pro G2 w/ B4 Mount Question
Posted: Fri Jan 07, 2022 3:56 pm
This is my first post on the blackmagic forums so thanks in advance for the help!
I have a set of UMP G2's with the B4 mount attached and a Fuji XA20sx8.5BERM-K3 ENG Lens attached to that mount. I've added the additional .10 shim along with the .50 shim that comes when you remove the EF mount (for a total of .60) but I cannot seem to get the lenses to be parfocal and they also have some chromatic aberration issues right before / after hitting focus.
What could I be doing wrong?
