60x is ok for some things, but not for true microscopy. However, a flattish pocket microscope capable of magnifications up to 400x with moderate aberrations would be good. There are no current really good "field" microscopes available owing to the conventionality (objective, eyepiece) of microscope optics. There have been a lot of plans for them, but none have come to fruition. I'd pay $500 or so for a good one.

I think it would be more attractive with some adjustment on lens-sensor
distance, so that you could do (say) 5 to 60x The ring illuminator is
good, though.

The way to go for affordable amateur field microscopes must be ones that
bluetooth the image to a phone, thus letting you get the primary optics
into inaccessible places. Over the years (when I was doing more field
work) I collected a few cheap USB microscopes to use with a laptop.

Just unfortunate that the last decent field microscopes were made in the 60's and 70's by Nikon and Swift.
