(The “jellyfish” was something on the lens.)
No it’s not. If it was then it would be constantly aligned with the cross hairs trying to get a lock.
Like I said, I saw them all the time.
Some were on the inside of the camera from something that got in when the technicians refilled the nitrogen. (Nitrogen being inert and would keep the lens from fogging up with temperature changes).
It's more pronounced on cameras such as these that can zoom in from miles away.
