K-7 and lens distortion correction

Everybody says the K-7 saves images faster than the k-20d, but that wasn't my experience. Actually, it was way slower than my K20D. This morning, I tried an old Nikon (shame) lens on the K-7, and, lo and behold, the image was saved almost instantly. So, being as smart as Sherlock Holmes:oops::oops::oops:, I investigated to try to see what the problem might be. And, since I'm smart:roll:, I figured it out. I had 'lens distortion correction' and 'chromatic aberration correction' set to 'on'. The dcamera takes a faily long time to process the information, even in RAW, so if you find your K-7 kind of slow to save or display an image, look at those two parameters first. Just in case you're no Sherlock Holmes:lol: :lol:. I guess now is as good as any other time to go and hide before you start throwing empty beer bottles at me.:mrgreen:

I use PhaseOne's CaptureOne4 Pro. The current release doesn't support PEF which I prefer mainly because they have a particular camera profile and their own lens correction optimisations.

You can work with DNG in CaptureOne but it's considered a default RAW file without any optimisations (read more work). And no the lens correction data doesn't seem to be implimented in DNG, at least with CaptureOne4
