Hi everyone. I have some problem with mentioned lens. Here is the link to my youtube video that shows problem: https://youtu.be/WGu1p4qwhGU . I have a lens mounted on D5300 and besides clicking noise and image shaking in viewfinder (shown in video) there is also a problem when I switch camera on and straight on to live view, autofocus does not start to work at all but if I switch camera on and press shutter release button half way whilst in viewfinder it works and after that I can go to live view and it will work there as well. Any help please ?
Many thanks.
