I use this lens a lot. Friday was the last time with zero issues. Today I did a flight and all of a sudden the lens wouldn't auto focus or manually focus. I tried my Olympus 25 and 45mm lenses and they both worked no problem. When I got home I updated the DJI GO software to the latest, plus there was inconsistent software warning that suddenly came up so I updated that also. Still same problem. I then cleaned the contacts and reset camera settings and still same problem. My other lenses continue to work with no issue but the 15mm will not auto focus. Nothing happened with the camera or lens since my flight on Friday so has anyone else experience an issue like this?
