How Do Zoom Lenses Work on Cameras?

The "big three yuan" lens refers to the collective name of three zoom lenses with a constant maximum aperture of F2.8. One of these three lenses is responsible for super wide-angle, one for standard zoom, and one for telephoto. Together, the three lenses can cover the most commonly used focal lengths from super wide-angle to telephoto (Canon and Sony are 16-200mm, Nikon is 14 -200mm, Pentax is 15-200mm), so it is called "big three yuan". At the same time, only the highest-end constant-aperture lens can be named the "big three yuan".
