It's either a hoax or a cctv lens.. Seen a cctv lens from tokina ranging from 10-500mm f/4.0.. Would be cool if it were to be a camera lens..

Is it possible for a lens to have an aperture of f/0.9?

No... that would mean the aperture is larger than the lens element. But f/9 is more likely.

Hrm.... This one is a bit odd for me too. In theory it's possible for it to be mechanically larger than the lens, but I don't see any benefit.

:dunno: but i came across this f0.95 :dunno:
not sure how it actually works
The lens iteself is the aperture lah.. the f-number is the focal length of each element divided by the diameter of the element.

Aaaah.... So the lenses are actually bigger than the focal length. Ok.
