Pentax K-1 Mark II - corrections of Lens distortion d't work?

I have recent shots from Pentax K-1 Mark II (PEF) with lens - Irix 15/2.4 and Sigma 35/1.4 Art… But with installed DxO Optics modules for this lens, the automatic correction of Lens distortion (geometric distortion) d’t work… btw… for Pentax K-5 correction works fine… (

Hello @sergeA,

There was a glitch in the modules release, sorry for the inconvenient.
We will today redeliver some modules for Pentax K1 Mark II, including Irix 15mm f/2.4.

When K-1 was released we had to calibrate lenses for full frame, before we had only APS-C calibration but we don’t own all lenses so some are still only for APS-C mode. We will get the lenses we still miss in full frame mode but it take some time and we have to deal with other priorities.

Best regards,

Thanks for the quick reply Marie!
Just verify the work of lens distortion correction for K-1 - all works fine… This problem occurs only for K-1 Mark II + any lens… I will wait for the PL updated version / modules…

Also will be great, if the future versions of PL can recognize the pixel-shift shots and correctly process these PEF-files as in SilkyPix Developer Studio.
btw… the code examples for pixel shift demosaicing algorithm are already exists - https://github.com/Beep6581/RawTherapee/blob/dev/rtengine/pixelshift.cc

UPD… just reload modules (31.10.2018 / 20:05). All is OK… Thank you!!!
And now I will add to my recent and future gallery shots the additional info about the version of my RAW editor - DxO PhotoLab - for ex. https://500px.com/photo/280577753/autumn-in-the-hapsalsky-beech-forest-1-by-serge?ctx_page=1&from=user&user_id=81777 + https://www.dpreview.com/forums/post/61863516 )
