Strange looking halos around high contrasted silouettes, maybe caused by purple fringe of the lenses. See picture below.
Also the edge sharpening looks strange around the lightest branches. As if there were blocky pixels.
Clarity doesn't affect at all.
If I turn down Highlight slider, I think that turn down is to get back to 0 value, the strange halo disappears in a white sky, but there is a blueish surrounding (like a fringe) around the high contrasted part. What I want is to recover the sky.
