Just starting to sprinkle. This a block and a half up from our place. I stood under an awning to shot it. What I was testing was the blurry spot between center and right edge (top her) of the frame. I had several theories, none of which held up, It is either something on the lens (and it's so small I can't tell without a loupe) or just a defect. (zoom to "O" and look near the platform above the tank to see what I mean).
