Do the wider-angle lenses that can go with the Panoraflex camera, such
as the 75mm and 90mm lenses, need a center filter to reduce vignetting
or do modern lenses not need it?
Is the 2cm shift enough for architectural work when using the 75mm and
90mm lenses?
Not sure if this should go in the large format category. Can 120 or
220 film use be "large format"?
