Not a compact prime, but interesting to have a look at:

The 0.384 lens is not very interesting Cassius it has its focus inside the lens - not good for DSLR user. With a camera with sensor head on a cable out would usable.

The f/0.5 lens is more interesting, even has larger image.
But likely very expensive. So I stay with my f/0.58 lens, also rare and not good usable.
