What is 5x and 12x magnification?

5x and 12x magnification refer to the degree to which an object appears larger through an optical device, such as a microscope or binoculars. A 5x magnification means that the object appears five times larger than its actual size, while a 12x magnification means it appears twelve times larger. Higher magnification allows for more detail to be seen, but it may also reduce the field of view and depth of focus.
