F5.6 fixed aperture diagonal fisheye for APS-C format. 50mm diameter x 32mm length and 120g make it an interesting lens for drone applications and similar, quality has to be investigated.
It DOES NOT HAVE AN APERTURE RING, aperture being fixed at f/5.6.
It is not clear if the 172 degrees of fov are on diagonal or on the long side of the frame.
As always it’s a “dumb” lens, no chip or electrical contacts to the camera. It could be a little more than a recaged cctv lens, since its coverage is at least APS-C.
