Purple Fringing: A losing battle.

I have been having problems on and off with my Tamron 70-300 lens with purple fringing. Some days it works fine and others it has massive purple fringing. I realized I tend to have more issues if I am not shooting in optimal light. I know it is not an issue with my camera because during airshow I shot with a Tamron 70-300VC and I had no issues at all.

Recently, I went to Atlantic City airshow (which has very bad lighting) and a lot of my pictures had purple fringing I tried to remove it via Hue saturation and it ruins the sky and darkens the plane a lot and leaves minor noise and artifacts around the plane. Here are some pics of my attempt:

If you want a closer look I uploaded a zip file you can download HERE

I know there may not be much I can do to fix the pictures but any suggestions are welcome!

Also I am probably going to get my lens looked at but it looks like I will upgrade and just keep this one as a last resort backup.

Thanks!

Hi. Purple fringing does happen in these conditions, even sometimes with the best lenses. The high contrast just causes too much aberration and the light "breaks down" so to speak.

I tried just a normal edit, at 1000pix wide. Hope you don't mind but only way I seemed to find to post it here was to put in on my Flickr.

I did a standard crop, spot removal, adjust levels and sharpen. Looks not too bad.

The others - the Sea Knight is too blurry, and the KC-10 too washed/out or flat to adjust.

The purple fringing was not noticeable at all on my first lens from this thread.
My Cheap Tamron Lens thread
until I broke it. I took it to get fixed but the purple fringing was really horrible after a complete rebuild. They ended swapping out the lens and I was told it was almost never done. Now it is a backup as I have the Bad boy 70-300VC on the left!!!! My middle lens now has 5 pictures on it total!

The Photoshop ACR and LR 3.x Lens Correction modules do a great job of controlling the CA and other optical imperfectionspretty well. Give it a shot

alevik: I don't mind at all that you uploaded it to Flickr. I saw a lot of improvement in the edit. Thanks

gonzalu: I'll give it a shot.
