like many other owners of this lens I got a problem with my Panasonic 12-35mm/F2.8 ASPH X lens. When mounted on my GH2 ( it is happen also on GH3 bodies ) and placed on a tripod, even with Power Image Stabilization OFF, the image frequently shimmers. There's a lateral movement in the image, and there is no movement near the camera to cause camera shake.The camera is on full manual mode, AF Manual S or Continue , stabilization OIS ON or OFF but shaking still here.
It's as if the image stabilization is on or the lens motors are moving, when obviously they shouldn't be. When the IS switch on the lens is set in the "off" position, the camera correctly reports that image stabilization is off.
PLEASE PANASONIC FIX THAT
