Itís turned as far as it can go- until it clicks/locks into place. Iíve remoubted the thing about a hundred times by now haha... I really wish I had another af lens with me to test and rule out a fault with the camera!! :/

The sensor is definitely capturing images; I can take photos- the lens jusy makes no attempt to focus, and Iím unable to focus manually. Power issue I guess? Or the lens has somehow jammed since its last use?
I just tested an out of warranty 55-300plm on 2 K-3's and on my K-3II, no focusing. I used this lens 1 month ago so I know it did work on my K-3II. The manual focus ring is electronic so no direct coupling with the internal focus elements. Estimated cost of repair is $60 less than a new lens. I would request warranty service for your lens, a new lens has been ordered to replace the faulty one I tested.

Another shot in the dark, and not a solution to the problem, but there is a known risk of the vibration of aircraft shaking screws loose in cameras and lenses - not that it's ever happened to me - does anyone who pulls lenses apart know if there is anything that might make the lens vulnerable to that in terms of this outcome?
