The dilemma is the flange focal distance. Canon EF is 44mm and Nikon F is 46.5. Pentax K-mount is 45.46mm. As result, any adapter needs to have corrective optics to be able to focus to infinity and if you want AF to work, the various contacts will need to be fitted and configured such that the correct data is transmitted from the lens to the camera. I do not believe such adapters are available.
