I made a test with the Pentax K-1 Pixel Shift mode and Panorama merge feature in Lr6.
Those panoramas are made of 4 horizontal images with and without Pixel Shift mode enabled (Note that each pixel shift image is a in-body merge of 4 images).
You should download the full size image to better see the details and compare it to the next image.

Both taken with FA*85mm f/1.4 @ f/8, 200 ISO, exposure varied between 25s and 30s (my error)

I really like these two panos, good lighting and showing great detail.

Thank you eaglem... I tried to get what I saw that night... It's maybe just a little more exposed than natural...
