Zeiss Ikon however, withdrew from camera production about 1975, while Pentax went on and introduced the K-mount to be a feature of all their subsequent cameras. They made the mount available for other camera manufacturers as well, hoping for a new industry standard. Some manufacturers adopted it, but due to different requirements regarding electrical contacts, no real universal mount has been obtained.
