Hi,
I recently encountred this problem whereby when I click the shutter button and when the camera tries to focus in the viewfinder the image shakes and you can hear clicking noises as it tries to focus. The camera I use is a Sony A6000 and the lens is the SEL1670z. It only happen when I manually zoom and when the lens is extended. Its very annoying because as the camera is about to lock in on focus it suddenly shakes and the camera has to try to refocus. I can still take pictures but if video forget about it. Shakes too much when focusing. Anybody else encountered this problem? Please help.
