With SteadyShot ON,when the shutter button is half pressed, I sometimes get a high pitched metallic whine from the SEL18200LE and the picture in the monitor/viewfinder vibrates and jumps around (more noticable at longer focal lengths).

I can get this to happen when in manual focus, so the autofocus doesn't seem to be the cause. Once the lens starts doing this you can stop it by turning SteadyShot OFF, but it will recur as soon as you turn it back ON. The only way to really stop the vibration is to reset/park the lens mechanism by powering the camera off and back on.

I returned one SEL18200LE with this problem but it's replacement behaves the same, suggesting the issue is with all SEL18200LE (Ver. 02) on A6500 (Ver. 1.00).

Has anyone else seen this problem / know anything?
