  This image is not stacked and is a single image ....... there is a steady fall off of sharpness from the point of focus ...... 
[color=#1c3b5f] IMHO the image is heavily cropped to maintain the DOF.

I'm not so certain about this, dave. With an aperture of f/5.6, I also get a smoother transition at the end of a stack. And that's the thing I complain about, you can't be sure about the used aperture - no EXIF and Laowa/Venuslens didn't care to at least ask the photog.

But then, the lens is made for APS-C, so DoF can appear a bit larger.

   I am, there is a gradual change of focus ..... indicating to me a decent amount of cropping to get the greater DOF of a smaller sensor at around F11-16. At no point looking at the right leg from top to bottom, is the focus equal ....... giving a look of a cropped M4/3rds ( I mean that in terms of the cropped size of the APSc sensor)
