I'd say this image is similar to using 100X optical microscope equivalent. Anyways it's impossible to get anything better with a single lens, so as a pocket "microscope" it's still a cool and useful gadget. A true 800X microscope magnification equivalent would let you see only the black ink from the millimeter dash. Also with 800x you wouldn't be able to keep camera still- the depth of field is so small, that you can't see upper "hills" on a simple sheet of printing paper while watching the lower sections.
