X7 w/ 16MM Lens Manual Focus Problem

[Motion In Film]

I have the 4 lens set and all are working well except the 16mm. The MF knob on the Cedence will not control the focussing of the lens. When mounting, I have turned the lens counter-clockwise slightly to make sure it is seated properly.

Is anyone else having this problem?

Try wiggling the lens in place when its attached to the X7, it fixes my autofocus issues.
