2. What is lens equivalency?
3. If you had a full-frame sensor and your cousin had an APS-C-sized sensor, how would you explain the differences between the cameras and lenses to your cousin?

Crop factor is the concept of a smaller sensor resulting in a more zoomed in image given the identical focal length. Lens equivalency is when you take the crop factor and multiply it by the focal length of a lens. An ASP-C sensor with a crop factor of 1.6, shooting a 50 mm lens, would give the same angle of view of an 80mm lens on a full frame sensor. The full frame has a wider field of view with the same focal length, so if you wanted to capture the same look as an APS-C without changing the distance, you would have to use a longer lens on the full frame.
