In exchanging emails with another large format photographer, I learned that he's using a fresnel focusing screen he bought from Bill Maxwell of Maxwell Precision Optics in Decatur, Georgia. I spoke with Bill at some length today. He's very helpful, and seems to know what he's talking about in terms of the various compromises, and advice with respect to getting an appropriate focusing screen. Has anyone had experience using one of his screens?
