What happens when you try to build a 14-500mm f2? What if a single camera lens could do everything? Imagine a 14-500mm zoom lens with a constant f/2.0 aperture , an ultra-wide to super-telephoto monster that could replace an entire bag of lenses. It sounds like the ultimate "one-lens-to-rule-them-all." But there's just one problem: it's physically impossible. In this video, we break down the science behind why a 14-500mm f/2.0 lens can't exist, from the physics of f-stops and entrance pupils to the extreme challenges of optical design.
