That's a Moire! (Nikon 1 V1)
When the sun hits your eye like a big pizza pie, that's a Moire!*
There's just a smidge of color artifacts in the textured surface of my brother's Olympus OM-D. And along the top edge of the grip too. Hmmm, I never invested the existence or strength of the Nikon V1's anti-aliasing filter before. I think I should run some rigorous tests....nah, that's not my thing.
