The common reason for such a thing is that dust in the air reflects the light (most common when using flash.)

I'm not an expert in what that looks like, but I wouldn't think it looks like that. Very weird!

Ghosts.

(Couldn't resist. :roll: )

Your description reminds me of the condition in eyes known as "floaters," which are bits of material in the fluid of the eye that literally float around. Sometimes they're seen, sometimes not. Could there be some dirt or fluff that got inside the camera?

Default Looks like

Lens Flare to me. Lens flare can be caused by the front lens element not being recessed (or without a hood) and light refraction off that lens. Some of them outdoors can be corrected by changing tha angle of the camera to the light source (direct or reflected) & or adding a hood &/or polarizing filter. The first thing I would look at is...does your front lens element extend outwards in a convex shape? If so, it's most likely the source.

I agree with Kalypso in the lens flare theroy. The next time you see the spot change your angle of the shot and see if it disappears.

It might also be a droplet of water on the lens.

isn't that a reflecting dust particle which reflects the light of the flash which is used? (I guess you used the flash?)

Default Flying jellyfish

The object clearly has a ribbed, ringed, spiral structure. Are we the victims of alien visitation or crop circles (or something)? Or has anyone seen a micrograph of such an object? If it was a dust particle, would it have been so nicely in focus, to show its structure?

Please can we see some more examples, as they are said to occur occasionally, and sometimes in groups?

We need Sherlock Holmes to solve "The invasion of the spiral-ribbed flying jellyfish".
