A case in point; today's macro shooting with Laowa 25mm f/2.8 Ultra-Macro and the Z7. Subject here are cross sections of the stem of Potamogeton natans (Pondweed) done at 3.5X. The scene is about 6 mm across. All done on Linux using Photo Ninja and Zerene Stacker (apart form the final step of uploading to the web, on one of my Windows boxes).
The Laowa lens is a sharp performer, but I could do with less chromatic aberration.
