Imaging of three-dimensional objects by lenses and mirrors is sometimespoorly indicated in textbooks and can be incorrectly drawn. We stress a needto clarify the concept of longitudinal magnification, with simulated imagesillustrating distortions introduced along the optical axis. We consider allpossible positions of the object for both a convergent and a divergent lens,producing real and virtual images. We also discuss spherical mirrors,elementary telescopes and microscopes.
