My guess too,
For a long time I thought the Distortion Correction option could only be activated with a DA lens mounted (ID chip inside?)
but a recently acquired Tamron 17-50mm f2.8 also allows it ON and like original poster
Manuel mentionned,
also takes a while after each pic to record/display images. (not sure if it actually does any corrections?)
When mounted to my K-x/K-r, my other non-Pentax lenses (1xTamron,1xSigma)
don't allow the Distortion Correction option to be activated, only the above mentionned 17-50mm
