It is hard to say for sure, but I'm noticing in the "purple orbs" examples I think most of those blobs show aperture blades which means they are reflections past the aperture stop and jive with my half-baked theory...

My thoughts exactly, all purple orbs i get are clearly shaped like the aperture. This dismisses the theory of reflections forming up in front of it. Also the tests from Anders show it's clearly reflections with a specific wavelength, which really makes me think of either a rear element coating problem, and/or a sensor tuning that amplifies this wavelength specifically...

I don't think I show that the reflections have a specific wavelength. How do you arrive at this conclusion?
