Many firsts for me on this image:
First time using a DSLR to scan medium format film. Conclusion: the Epson film holder I used here doesn't quite keep the film flat enough at the edges, but it does well in the majority of the center.
First time doing image stitching: this image is 2 frames combined in the Hugin software. It does have a bit of a learning curve, but not too bad. The result is a nearly 9000 pixel on the long side 6x4.5 file, which is the size the Epson flatbed gives for a 6x9 at highest effective dpi.
First time trying the Shanghai GP3 film in 220 format: they are the only current maker of 220 film. I had previously tried it a decade ago in 120. The film is a bit curly, like old Fomapan, or Aviphot. But there was no mechanical issue as it ran through the camera. It's nice to know there is a viable alternative to expired 220. There was no problem getting it onto a plastic Paterson reel, steps were taken to cut the beginning and end so that no taped part remained. I noticed the tape was slanted, this film appears to be taped by hand rather than by machine.
All in all, this wasn't really an image that needed to be scanned in this much detail, or even to be shot in medium format, but it served as a test.
The quarry in Shepley, West Yorkshire, shot from Piper Well Lane. I wanted to shoot this in the morning, into the sun, to isolate and accentuate the more interesting rocks against the deep shade of the quarry wall.
Shot on new Kodak Ektachrome 100 with Contax RX camera and CZ Distagon 35mm f2.8 lens in 2018. Digitized with Sony A7R3 camera and Sigma 70mm F2.8 DG Macro lens using Pixel Shift mode.

This a wide open center shot of the above lens. I used pixel shift and micro contrast sharpening via RAW Therapee.

Pixel Shift with Nikon NX Studio
Focus stacking with Helicon
I was asked by Nikon to test shoot the 3.0 FW with a special interest in the new ability to use Pixel Shift and Focus Shift at the same time.
Pixel Shift is an option where the camera moves the sensor during a series of captures. This series is then merged in the Nikon NX Studio software. In this case, the pixel shift option was set to the maximum capture option of 32 images. The camera exposed an image then moved the sensor… about half the width of a single pixel… and exposed the next one. For 32 images. Those 32 NEF (RAW) files were merged into one massive NEFX raw file that now has a resolution of about 180,000,000 pixels.
Focus Shift Shooting is an option where the camera makes an exposure then shifts focus to a different plane and makes another exposure. The cool part is that the camera is automatically setting the shift movement so that a series of images can be stacked on post in such a way to increase the depth of the PLANE of focus. This results in a subject the can have a nearly unlimited amount of the subject focus. Not just more depth of field, but depth of actual in focus.
The Z8 FW 3.0 is the first time anyone has offered both at the same time on a full frame professional camera.
