Is this a common problem with the 5D mkIII?

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.

Thanks!

In my other example, with the kookaburra, that probably wouldn't work as well with its green background, though the aberration is much slighter.

It works fine.

It works fine.

Sure does- thanks for pointing that out!
