I think my Ricoh Theta SC lens might be scratched. In this photo (you might need to click the image to see it in 360), to the right of the track, the top of the hedge looks cloudy, whereas the bottom of the hedge has some detail.
I don’t use a case. I assumed the lens was glass, and as long as I rested the camera on something soft, I’d be OK. I think the lens might have a coating that has come off.
I assume the only option is a lens replacement (or new camera).
