This
is a C-mount lens, a mount for movie and security cameras. It doesn't
cover full format, you have to set your camera to APS-C mode. 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. It's small and cheap, so don't expect high quality, it's soft at
the corners. Quite some fun for portrait sessions.
