Pentax K-3 Purple Edge

I'm currently switching from Aperture to C1 and my photos from Pentax K-3 are showing a purple edge on photos with a white background. This doesn't show up when my RAW (dog) files are processed with Aperture or Photoshop.

Could C1 be catching a sensor issue or is it more likely to be the C1 camera profile for the Pentax K-3?

  Did you capture in PEF or DNG, as Pentax as I recall call both of them as RAW

  Just checked by myself using latest C1 software.
  With DNG Raw file, was able to reproduce issue that you talking about.
  Definitely looks like a bug in how software handles DNG, pls open support case with C1.

  Yeah, I just switched to .PEF and had no problems. I will report the issue to them. Thanks for your help!

  Never noticed it, but I have that issue as well (with a Pentax K3). And not only on the right side of white backgrounds but also on the top of picture that has a white, black white background across the black section. Opening the raw in preview shows no purple edge.

  Phase One Support let me know that officially they only support the K-3 w/ PEF raw files.

  Hmmm...
  
  So this is an out of camera DNG?
  
  Because if it is, I'd push back on that statement. The Capture One Camera Support page confirms "file support" for the K-3. As this is a K-3 file, I'd expect it to be supported by Phase One.
  
  There's nothing on that page - or anywhere else on the Phase One site - suggesting that in-camera DNGs are conveniently "unofficially" out of scope.
  
  Go back to Phase One, Danny. You have a legitimate expectation of file support as advertised, and DNG is unequivocally in scope of "file" support.

  If this indeed from the in-camera DNG, it is a clear-cut bug. Please create a support-case and be sure to provide the raw-file, so we can verify a future fix.
