Has anyone else had an issue with FOD (foreign object debris) on an inner lens on their EP5s? I have cleaned the ocular and objective lenses over and over with a Zeiss cleaning wipe and the debris remains near the periphery of the lens. At approximately 7x zoom, the debris falls out of view of the scope. Namely, I have 3 locations with debris at the 11,12, and 3 o'clock positions respectively. I cannot see any debris on any external surface of either lens. If anyone has a shared experience, I would appreciate them sharing.
