Depending on your smartphone, camera module and lens only a small part of the image can be used, which as a poor picture quality considering the price each should be as clear. Lighting is not very environmentally friendly with button batteries, either with white or blue light (sometimes lit something like under a UV lamp, but that wavelength is that?).
I wonder, however, who can keep his smartphone at about 60 times magnification for long enough quiet about the object, in order to focus, then find the desired image area and then can trigger the camera without that image out of focus or to compose the shot lost has.
