I noticed that stacking with DNGs in this case has significant smearing whereas the result from in-camera JPGs is sharp in comparison. It appears that aligning has not worked well. This fragment is towards the edge of the image but all parts seem to suffer to some degree. This was with C2 but B84 and C4 gave similar results.
The shot was on an XT2 with focus bracketing using the smallest lens shift and electronic shutter. Although the gold area is quite shiny, there are plenty of high contrast areas. Attached is the JPG stacked reference, DNG and difference from JPG and DNG fragments aligned to the bottom right. Helicon alignment was using default settings. Choosing the slowest alignment settings gave no benefit.
Catherine, any suggestions to explain why the JPG processing was better in this case, and settings to try adjusting?
JPG
DNG
DIFF
Why is this DNG processing smeared and JPG not?

Could you please send us source files in .dng and .jpeg? We'll be happy to have a closer look at it.
