I bought the lens recently. But I was getting Err 01 ( connection between the camera and lens is faulty). Upon some investigation I found out that the aperture blades are not moving as supposed to. They function completely okay both in max zoomed in or zoomed out state. But they does not move at all in between zoom levels. Is there any way to fix it apart from taking service from a service center? There is no official Canon service center in my country.
