This Rokinon 8mm is proving to be a fun lens. I took it out of the box, stuck it on the camera, and went outside. I set the aperture to f11 and the focus to infinity, shutter speed to 1/80 and ISO 200. Really hard to get an OOF image with this as long as your subject is more than 10ft away. And the distortion isn't too bad if you keep straight lines away from the edges.
Just a couple boring shots of my street, and then one with straight lines closer to the camera.
