Kinda opposite direction, with the launch of new very high res ("50 megapixels") Sony a1 I started thinking that with a macro objective you could use it as a sort of low-magnification microscope. With a 1:1 macro, if you crop a 4k section from the full-resolution image and draw it on a 32" display you'd get 40x magnification (sort of) if I did my math right; 1px on screen would correspond to roughly 4µm which gives some ballpark on what sort features you could see with it. But it gets better still, there are at least some 2:1 magnification macro lenses [1] out there, those would double the magnification you get.
I haven't really figured out how that compares to "real" microscopes, or even like the $100 chinese digital scopes.
