F 4.

F 16.

Closest focus
is only 14cm from outermost edge of the lens, F 4. Focus on the program wheel of the camera.

This is a C-mount lens, a mount for movie and security cameras. You can buy the lens with an E-mount adapter. As C-mount focal flange distance is shorter than Sony E-mount, it comes with a slightly recessed adapter. There was even a close focus ring and a shade in the package. It's a basic lens. Aperture has no click stops and infinity isn't at the infinity mark, but it focusses to infinity nevertheless.

It's a bright lens and astonishingly sharp in the center already wide open, but very soft at the corners. At F 4 corner softness is only slightly visible. 
At F 16 it hardly gets blurred at the edges due to diffraction, much better than other lenses. Diffraction is a problem of the APS-C sensor size, not the lens (see comparison page). It's small and cheap, so don't expect high quality, but you have a unique control of corner softness via the aperture. Quite some fun for portrait sessions. It has some close focus capabilities, even without the close focus ring.
