The photographic lens is what creates the optical magic of bringing a subjects image to focus on to the image plane (that is the image sensor or the photographic film at the back of the camera). It refracts the lights rays, condenses them, and brings them to focus. The photographic lens is responsible for all the magic that happens inside a camera.
But did you know that the photographic lens is actually the total of several optical elements all working in tandem?
