I was browsing through a set of files from my microscope cameras when I came across an unusual folder. Obviously I had tried a specific 5MPix camera for non-microscope use and had hooked up varous likewise non-miscroscope lenses to it. Among the test samples I found this, taken with the Ultra-Micro-Nikkor 28mm f/1.8 and according to the text notes accompanying the image, at f/4. I also found an excerpt from an old Kodak pamphlet that fitted into the overall concept as it were. Oh, how difficult it is to predict even the near future !!
