This microscope works well. It's not as good as Nikon or Olympus microscopes, but it's not too far off the mark and is excellent value for money. The illumination of the light field is good, there are no problems with backlighting. Darkfield is a bit trickier, all settings should be fine. I would like cross-polarizing filters that give a better image of unstained bacteria than darkfield. 40x, 100x and 400x magnification provide excellent images. The 1000 and 1000x oils are somewhat limited due to the very limited depth of field. I bought a 2X microscope adapter for Sony E-mount mirrorless camera (NEX/A7/A9/QX/VG). I get great photos with the Sony A6000, but with a smaller rectangular field of view.
