Don't know how you did that, but I'm still laughing yet.

I've given you a rep point or two for that.

Thanks for all the fantastic responses.

Does purple fringing go away with "apo" lenses or is it a function of how wide open the lens is?

Purple fringing can occur with any lens in high contrast conditions. It can be mitigated by stopping the lens down. It can also be dealt with in post-processing.

Purple Fringed photo from the king of PF, the Tamron 70-300

Correcting this amount does have a couple side effects but it can be done.

Corrected.

From the Pentax DA12-24

Trust me, it's there.

Screen shot during post processing.

Final corrected image

I can make Any lens fringe.
