I have heard this lens makes a constant humming sound, as if the stabalization motor is running constantly. I learned this from a photographer that took it to shoot a wedding (regularly shoots weddings) and he noticed it, so went back to the store and showed them and the store said that it was a normal characterisitc of the lens. He found it very distracting and returned it.
Has anyone else here noticed a constant humming coming from the lens when the camea is turned on?
