It’s the kind of article that makes me more aware of how little I know — and the comparison of lenses and the human eye is a reminder that my human eyes will likely soon need added lenses themselves… glasses, that is — but LensRentals founder Roger Cicala writes a fascinating discourse on optics.
Posted at enthusiast site PetaPixel, the article “followed an online discussion about whether a 35mm or a 50mm lens on a full frame camera gives the equivalent field of view to normal human vision,” Cicala writes. “This particular discussion immediately delved into the optical physics of the eye as a camera and lens — an understandable comparison since the eye consists of a front element (the cornea), an aperture ring (the iris and pupil), a lens, and a sensor (the retina).”
