Good Afternoon, Michael,

I've used a 135 Componon on my Beseler MCR-X for around forty years with no problem. Several years ago, I bought a 150 Rodagon, thinking that using it would mean more of a given image would be projected by the center of the lens, supposedly the best for quality. Somehow, I never got around to mounting the 150 in a board! Maybe someday I will; maybe I'll notice greater image sharpness--but somehow I doubt that it will make a significant difference.
