I had to take this camera back as the 14-140 lens is very noisy. It makes a constant whirring/churning noise and it didn't seem possible to switch off whatever it was doing. This noise is audible when in a quiet room and as such is picked up on video recordings. I tested the 14-42 lens and it does not suffer from this problem, it does however make a clicking sound. I can only guess that these noises are created by the gyroscope in the lenses. Real let down as it took ages for me to round it down to this camera.
