What is so special about this lens?
Why can't other manufacturers create something similar?
It's one of the largest relative aperture lenses in the history of photography, which means it can allow cameras to shoot in very low light. It was designed and made specifically for the NASA Apollo lunar program to photograph areas of the moon not lit by the sun.
I suppose other manufacturers could make it (though Zeiss sort of is the lens company), and some have made similar or even faster lenses, but it probably would be very expensive and there's not much of a market for it.
