I just mounted a 159mm Wollensak wide angle on the Intrepid 8x10 MKII using a flat Sinar board. The lens standard mounts in the second hole away from the film plane. I'm not sure about infinity focus, but this can focus from about 200 feet away to very close. With all movements zero'd out, it doesn't appear that the camera bed gets in the way of the shot with the camera in portrait orientation. (One could always tilt the back back and then re-plumb to give a dropped bed.) I won't know for sure until I shoot a few sheets, but it looks like this will be a good wide setup. I'm really happy that I don't need a recessed board, as those make changing settings on the shutter more challenging.
