Some people have started to use X-ray orthochromatic film in their LF cameras. You might consider this option. The price is roughly half the cost of regular film. From the scans posted online this seems to be a workable option.

B&W I can do myself) no real local source of sheet film, and the cost difference, I am probably going to put that beautiful field camera on hold yet again. The lenses were That much again and since speed and portability may have a greater benefit than the extra negative space, I am probably going to go with the 645 format. Looking at the Mamiya and the Pentax the Pentax seems to be significantly more, especially the lenses. Both were prized in their day. Both can yield top results in the right hands. The Pentax lenses tend to be significantly more for the same focal lengths. Is there are reason I don't know or see? Does the Pentax have some advantage I am not finding over the Mamiya? I am looking at manual focus systems. Would that change if I went and dropped the extra for auto focus?
