Is 50x magnification good?

Excuse me, I'm curious about the statement "Is 50x magnification good?" Could you elaborate on what context this question is being asked in? Is it in relation to a microscope, camera lens, or perhaps some other optical device? Furthermore, the definition of "good" can vary greatly depending on the intended use. For instance, 50x magnification may be ideal for examining tiny details in a scientific experiment, but it might be overkill for everyday photography. Could you please provide more details so I can give a more informed response?
