Photographic magnifying glass

It is certainly possible to take a macro shot with a magnifying glass in front of the camera. The close-up lens sold in the market is actually this principle, that is, installing a convex lens in front of the lens, but the close-up lens is more exquisite than the ordinary magnifying glass.

Ordinary magnifying glasses are all spherical lenses, and a single lens is not designed to eliminate dispersion, so distortion, aberration and dispersion are very serious. Generally, there is no coating on the surface of magnifying glass, which reflects a lot of light and has low transmittance. ...

In short, you can shoot, but the imaging effect is very problematic.
