I have the one @MidwestGuy has and it does a good job. One tip: clip several tiny samples from plants, bring them inside and put on a piece of white paper. Then you can set up your pics without worrying about plant movement etc. You don’t need anything larger than a capital “O”.
I have the same one as @JPhoenixX , it does a good job bluetoothed to my IPhone, great trichome pics, just wish the focus was a bit more steady. You can zoom magnification right on the phone once scope is set up.
