No tilt.

Then, specially  re-built for the focus stacking with the movable camera and the fixed lens elements?

That's more like it, yes. The OM 28 was selected because its image quality holds up pretty well in the near range, despite a lack of CRC. However, it does have significant barrel distortion which can be a royal pain for the stacking software. There are also some colour aberrations most of which disappear in Photo Ninja. Image contrast overall is on the moderate-low side, but I prefer to rectify that in the final processing step. In this example, colours are a little off as the older Photo Ninja running on my Linux box hadn't an updated profile for the Z6. I have to make one later if further experiments are attempted. Or install a new version if there are any licenses left over.

In all, 121 frames were stacked. So the approach mainly is suited for stationary scenes.

Happy birthday!

   This I have to try. Cat eye AF. It does work even when the eyes are just slits.

   Z6, 50mm 1.8S @ 2.8, iso 1600 1/20th handheld with ibis on. Close to minimum focus distance. In camera b&w with minor shadow/highlights adjustments.

Jack, lots of triangles in that - nice - image.
Fons, a tribute to your father. Nice.
Paco and John, I prefer dogs way above cats but those images are lovely.
