How to disable permanent-active DOF preview in P1 645AF ?

Postby NNN635021504191960495 » Sat Jul 13, 2013 5:56 pm

After one use of the DOF preview button seems that the camera (Phaseone 645AF, firmware ver. 1.5) is always trying to check the DOF now before shooting (when the shutter release button is pressed only) or when power is on/off, and this always accompanied with the some "motor-like" 3-second sound from the lens (Mamiya AF 80/2.8 ). And even when the power selector on the camera is in the "Off" position, pressing the DOF preview button causes that sound. When I pull backward the lens release button on the camera, this sound is absent - when the lens release button in th "lens attached" position, when this sound can be heared in the situations described above.
What should I do to solve that situation ? Thanks in advance.

Seems that the sound comes directly from the lens... is it possible that the lens motor is going to be malfunctioned ?
