This was not the case for the previous LF lenses made by Kodak, Voigtlander, Zeiss, Taylor Hobson, and many others. Examples. Zeiss Biogon (aero recon version and..) were optically good at f4.5-full aperture, Kodak Commercial Ektars (Tessar) were good at full aperture of f6.3 then improved at two f-stops down and begins to degrade at smaller apertures. This generation of LF lenses were used by image makers with a different need and market. If one were to look at commercial ad images from the 1950-late 1960's -vs- mid-70's on, the style of commercial images took on a very different style and feel that in many ways were in sync with what those cultrual-social times were.
There are modern LF lens exceptions, Rodenstock Grandagon 35mm, 45mm, 55mm f4.5 had published these wide angle lenses had good performance at apertures larger than f22. Other examples are the current crop of digital sensor lenses where f22 becomes diffraction limited for a image sensor that needs more resolution that is possible with larger optically optimized apertures.
