Forgive me if my naiveté is obvious, but if Adobe is trying to mimic the basic profile each manufacturer designates as default to render the image visible after import is it possible that the scale or zero point assigned by each manufacturer differs? That is, as ACR interprets what Pentax assigns as “0” in default rendering may be equivalent on the ACR scale to a Nikon “40” to achieve equivalent amounts of default profile sharpening. As it is raw data imported one can then add or subtract sharpening to form their own desired profiles or import settings.

I can not answer this, because I use not a ACR. This only can answer users, which have this ACR and than they can say....yes, for Nikon the ACR default for sharpness is 40 and for Pentax it is 0. I can only say that my LR use a sharpness amount of 25 as a default for my Pentax RAW files....but not a sharpness amount of 0 !

I ask if this is Adobe ACR interpretation used in the studio comparison because I downloaded the images into ACR and get the basic sharpening setting of 0 for the Pentax .dng and 40 for the Nikon .nef. However, if I download the .nef directly into Nikon Studio NX convertor the default sharpening is listed as 0. I do not have a Pentax raw convertor to compare data there. Obviously the Nikon native convertor and the Adobe Standard profile in ACR assign different values for the default sharpening and a Nikon .nef 0 is a 40 as an Adobe .dng and a Pentax .dng 0 is a 0 as an Adobe .dng
