Lens or body error? 645DF & PhaseOne 120 F4 manual

[djordjez]

Hi all,

I hope I am not posting to wrong forum section.

Here's what bothers me. When I shoot wide open on F4 everything is just fine. As soon as I change F stop, i hear kind of "rolling" sound in the body, and curtain/mirror in the body get's stuck. The photo is not even written to the card. When I am using other lenses, there is no issue at all.

Any tip to resolve this issue?

Keep in mind that I am the only one owner of PO equipment in my country..so unable to try to another body, or other lens.

Thank you!

Dj.
