I’ve been shooting with the IRIX 11mm f/4 lens, which is a great cheap alternative to other ultra-wide angle lenses, but it’s absolutely impossible to remove the chromatic aberration in corners with PL3 without damaging edges of subjects in the center of the image by over-applying CA correction. In fact I can’t get rid of the green or purple CA whatever I try. Adobe Lightroom does have a lens profile for the 11mm f/4 and there I’m able to remove all CA easily, but I don’t want to have to use Lightroom at all.
Please, either provide us with a lens profile for the IRIX 11mm f/4, or even better, improve the chromatic aberration tool so we can clean up our images even if a lens profile is not available. Sometimes even when a lens profile is available, the CA can’t be cleaned up all the way. I see a bit of a problem in photos taken with the popular Nikon 85mm f/1.8G, something I can easily clean up in Lightroom. I’m sure there are many other lenses that could use improved CA clean-up.
