>>4206310>>4206314Huh, there's a smaller upright image of the 3.98 sign. That must involve a reflection off a curved lens surface. Does that lens have it even without a filter?
In any case it's very odd that the 3.99 sign has a different type of ghost, the usual inverted kind. I drew the meridians and they do intersect, off center. That shows how the image was cropped, right?
