Yes, I've read about this purple fringing, I already have the same problem with the 28mm f/1.8.

I need to lear how to get rid of that in post.

The first thing to know is that is generally occurs most severe in bright, contrasty areas at wide open apertures.

With Adobe Capture Raw (and, I would presume, Lightroom, though with some variation), you open the "Lens Correction" section, and then choose the "Color" tab. After that, it's pretty straightforward.

I encountered some of the worst fringing I've ever encountered last year with an outdoor wedding on a bright, cloudless April afternoon. There were some moments where I really, really wanted that beautiful bokeh that the 85/1.8 can achieve when it's wide open and the subject isn't too far away. About 95% of it corrected just fine in ACR, with no objectionable artifacts in the slightest.

The 85/1.8 is a well-respected lens that performs beyond some of the comments in these forums.

So, as I wrote in other posts, I got mine today and yes, I could indeed see that this purple fringing thing is not a myth... Pretty as ugly as the one I get on my 28 mm f/1.8.

Thanks for the tips with ACR. However, I don't think I will spend much money on post software. Can DPP do the trick as well or...? Until now I only tried to play with "Noise Chrominance" or smthg like that, but that did not help much. I am shooting RAW by the way.

It's been a while since I last loaded up DPP. Canon's earliest raw software was EXTREMELY limited, and many of us early folks looked elsewhere to third-party options that offered a bit more functionality. Bibble. Scott Professional. Capture One. Even Adobe's first few versions of ACR left a bit to be desired. But I finally climbed on board sometime around 2009 or so when Capture One radically changed its interface with one that left me cold. I already had Photoshop, so moving over to ACR/Bridge was natural.

ACR and Lightroom (they both offer similar output, and are based upon the same algorithms, but LR includes a lot of cataloging features) are both terrific packages that really make raw files shine. Even old raw files from outdated cameras improve can look better than ever when re-approached with these applications. About a year ago, after a bit of grumbling on the matter, I took the plunge and subscribed to Adobe Creative Cloud. I'm glad I did. Ten bucks a month for the best photo editing software out there, AND it's always up to date! I've seen photographers around here loose hundreds swapping lenses and gear in and out, yet they complain about spending $10 a month on industry-leading software. It's just a good bargain, period.
