Yes, fully agree that a Symmar S or MC will have better optical quality. The consideration here is to have a small enough lens that can actually fit inside the Linhof while closed. Bob Salomon from LFF convinced me that it is not worth the effort to find a focus cam that actually works with the lens. So I will probably just get a generic small 135mm or 150mm lens, make my own focusing scale on the rail, and use zone focusing instead of the rangefinder.
