Sincerely thanks @HKVISUALS sharing the experience for the Xtreme2885, below all the description and video are quotated from: https://www.youtube.com/watch?v=MJy_iBgN8xg&t=33s

"Chiopt2885 is a full frame zoom cinema lens that with the short experience I had with it delivers good performances overall, it loses a little bit of sharpness wide open, but starting at T 5.6, you get a bit of results. 

It has a smooth288 degree focus stroke for manual precise follow focus. I use it with the small wireless follow focus by pd movie, and It performed flawlessly, it is of course par focal. Breathing is almost unnoticeable".
