Virtually no lens that hits peak sharpness at f8/f11 (usually implies a lens with an imaging circle covering the 35mm/APS-C format size) will even stop down to f64, with virtually all of them the smallest aperture size will be f22.

These chaps where dealing with much larger formats and their corresponding larger lenses typically, the usual rules of thumb you might be familiar with from the majority of digital interchangeable lens systems or 35mm film don’t always apply. f64 would be fine on 8x10, as one example, and was often used on this format.
