        I use Lens X on Camera Y. It's a super good combo. I have bought the lens station on Amazon. Upgraded to latest firmware and I have full ibis now.

    I just got my 85mm and it does not work well on my Camera W. As others have noted, IBIS and BB+ shooting does not work.

    Anyone else have issues with continuous AF?

Update: I received the lens station today.
