I am pleasantly surprised for the wholesomeness and great quality of this microscope. Images are sharp and clean. I am happy I got it. It is fun and unpretentious, unlike my lab microscopes. I paired it wit a Gosky iPhone adapter, the one with the protruding tube to be inserted in the tube of the eyepiece or in the trinocular head. Helpful hint: First than anything else... Center the iPhone and Gosky adapter already pre-coupled with the light field of the image while it sits on the eyepiece position, for most control and perfect coupling. A little fiddling will show a sharp capture a circular image, uniformly lighted, without vignettes. THEN, you may photograph from the eyepiece (as if you still owned a binocular microscope) or, BETTER, now troubleless and already centered, on the trinocular tube. Best of both worlds: your eyes and your camera will be both satisfied, registering images at the same time, without the need to sacrifice observation to please your camera. Your diagnosis should be as good as if you were using a $5K microscope in a hospital or a university. Pictures included, taken on my inaugural session, are: Nail with fungi under the nail plate (medium power) and old plantar wart (high power).
