Hi,
BTW, should be quite an old patent application as it says Pentax
Corporation, not Hoya.
BTW, I've printed this app out and studied it's lawyerlike
descriptions, and it refers to no Pentax lenses or bodies that I've
seen yet, though the disclaimer at the end that it may apply to any
mounts that are similar does leave it open to the K-Mount design. The
only thing different is the use of two-prong tensioning springs vs the
three springs that are part of the current KAF-2/3 mounts.
