The image on top shows the Nikon patented optical desing of the 52mm f/0.9 lens (Source: Hi-Lows-Note). It’s very likely the 58mm f/0,95 will have nearly the same design. This is a highly complex design and for sure it’s going to be a very BIG and expensive lens. But still…very exciting and unique! The currently fastest autofocus lens is the Canon 50mm f/1.2.
