## Resource

Last year, we were so caught up in our own tenth anniversary that we completely forgot about the fifth anniversary of the K-Mount! While the K-Mount is most often associated with Asahi/Pentax, it was a joint invention by Asahi and Zeiss Ikon. Like the M42 mount, the K-Mount was intended to be a universal, open-source lens mount. But the partnership never materialised, and the two companies parted ways, with Pentax retaining the mount and one Zeiss lens design. Since its introduction, the K-Mount has changed slightly as technology advanced. To celebrate, the team is here to discuss the cameras and lenses for this iconic mount, from K to K-AF4!
