Totally opened aperture is different on every lens. Also I don't believe Nikon has ANY AF lenses that open to f/1.2

回复@Lime老虎:I agree. I did not mean otherwise. Whether Nikon has AF lens with f/1.2, I don't know. Canon has an 85mm/1.2L, selling for ~$1900 the last time I checked

回复@北美旅游快报:Oh sorry, that was directed at the person who said that the largest aperture was not F/2 but F/1.2 but I'm saying that the maximum aperature depends on the lens. I believe Leica still makes a Noctilux f/0.95

conceptually good article, technically not 100% `mathematically` exact, but who cares
