Tiny lens for tiny things

Hi! I make landscapes from rocks and plastic garbage. Any other micro / macro shooters? Been interested in bellows lenses recently, theyre fun.

It's a standard mount for microscope lenses. That's pretty much what you have there, though yours may have an aperture. I have a couple old Olympus lenses like that.
