Pull out my Lumix DMC LX3 this morning and started getting unusual (and new) System Error (Zoom) Looking at the lens, I noticed a little loop strip of thin plastic sticking up from between the inner and second lens pieces. (this is new. I'd never noticed this before. and since I take relative good care of the camera I don't know how it arose.) After turning the camera on and off several times and it still failed, I just pulled and removed the plastic bit. Afterwards the camera seems back to normal, zooming, focusing and shooting fine. So, what have I done? What was/is this bit of plastic?
