Here is a photo with my 85mm f/1.8 showing the purple fringing or LOCA effect, and the lightroom fix. Look closely and you will see the gray/white that replaces the fringing. The purple glow in the upper left corner has become white. Its a severe crop at 1:1
Great example. It makes an otherwise unusable image usable.
