Damn, have to try this.
I’ve tried it out! It is certainly interesting and I do recommend it, BUT it is somewhat of a specialized tool. The depth of field is super small so generally one needs to use a focus rail to take lots of shots and then stack them together to produce a nice output. And at this magnification the frame is extremely sensitive to motion… I have laminate floors, and taking a small step near the tripod causes enough shake to shift the image!
It has pretty poor dof, but getting this close to tiny creatures and other things is very cool. Have you posted pictures somewhere?
I got my focus rail recently and haven’t found a very nice subject for the microscope adapter, but I once I get some I will post them :-)
Here is a weevil I recently photographed using a more normal macro lens though:
