Re: 18-150 ll Purple Fringing Why?

Any 10X zoom is a design compromise, so with a backlit subject and using the lens at the widest end of its range is pushing the limits of its capability.

You have also used a fast shutter speed, so slowing that down and closing the aperture, will help to reduce this somewhat.

Fortunately, it's a well known effect and CA correction is widely available in many editing software packages,
