In Lightroom:

1: Load up your image
2: Grab the Slider for PURPLE SATURATION and pull it down until the fringing is gone. (Most images don't have that purple in them anyway so it's easy.. even in Lightroom)

If that doesn't work:

3: Grab the slider for MAGENTA SATURATION in Lightroom and pull that down..

These two methods work 100% for 90% of the time and when they don't it's only because there's a purple object in the picture. It then becomes a little more complex in that you either have to protect that object with a local filter or be prepared to lose the purple colour of object or keep fringing.

Thanks for the tip, beholder3. I find Photoshop actually works pretty well, but since the Nikon software is free, hey... I'll give it a shot! Maybe it'll be faster/better/easier.

Cheers,
Bobbo :-)

I use the very same approach all the time when shooting birds on tree branches. Since very few birds (at least in my yard) have purple colors, it works great.

It's surprising that the two colours mentioned are not present in great depth in most images.

My DA*200 F2.8 suffers PF at f2.8 to about f4 and I was relieved when I dicovered how easy it is to fix in most situations.

Actually, I find Lightroom very good at getting rid of PF, and the new algorithm in the LR4 beta does it in one click. Green & red fringes are much harder to get rid of, which is what I typically find in old lenses. Purple is no problem...
