Interesting experiment... Intuitively, it would seem that reflections
off the lens surfaces would align with the angle at which the light was
entering the lens. You can see that in the alignment of the two bright
flare spots in the lower left corner with the sun (light source,
obviously.) So - I wonder if the halo of small light spots circling the
sun are the result of lens flare or, as Bill Robb suggested, water
droplets or even dust specs on the front element. If they were
reflections off the different lens element then wouldn't they be in a
line, diagonal up towards the light source?

I didn't expect to see so many reflections from all the surfaces.
That's what I assume was the reason for all those spots. Right?
