I realize this is some kind of reflection but I don't know if it was caused by poor light poisition, non-use of a hood on the lens or what. The settings were iso 200, F20, 1/15sec

It might be from the non use of a lens hood creating a reflection on the lens surface.

Makes sense. The angle of the relection suggests that the sun was off to the side but in front of me.

What is on the ground. Looks like the remains of a fire? Or snow?

Are you using a polarizing filter?
I have seen this type of problem when using polarized glasses.

After looking at the original I found this on 1:1 It shows that something is in front of the lens (or inside) and was in focus at the sensor level. These are microscopic dust particles that you can see under weird light condition... in your eyes!!!! (if you learned to it).

I know, this is as weird a statement as I am.

What attracted my eyes to it were the dark spots in your picture and SURPRISE!!!

Of note (still looking at it and observing) all of it appears only where the rainbow is, from the upper right to the lower left (in the grass, less visible).

Lens flair due to sun angel in front of lens and dirty filter/lens element possibly. You should have seen that in the VF and shielded the sun off the lens with your hand if you didn't want it to appear in the shot. Polarizer...possibly.

After looking at the blow up I agree there is something like a neck strap in front of the lens or something trapped inside behind the lens.. that is weird. Let us know what it turns out to be please.

That is defiantly dust on the sensor. Take a shot of the blue sky and you should be able to see them. Refection in the sun rays might just be the dust in the air. Like a rainbow with water particles.

Dust that small does not appear on the sensor and does not create the light distortion seen here. Sensor dust is never in focus.

Sensor dust is out as an explanation.

The only thing that can magnify this and get in focus is a lens element. I would suspect this but having no reference image it is hard to make a positive identification here.

It is more likely that this is one in a million occurrence here.

Billybuzz can play the lotto with those odds!!! :shock: :mrgreen: :-D

Looks like diffraction off of an inexpensive uv filter

These are two other photos I took on the same day. They have blue sky and I can't seem to see the same effect. Am I wrong? I'll take a look at removing and cleaning the UV Filter to see if that helps.

If you look at the sky in the second one , you can still see it. I am still going with dirty sensor.

If that's true it's time for some maintenance.

Still say it is your uv filter also looks like snow on the ground with that sunlight filtering through the trees could of had a little condensation between the filter and the lens itself, along with the dust that was sticking to it.
