Just a follow up on my earlier serious answer. The 1.7x AF Adapter lacks the digital data pin, (seen here <http://www.bdimitrov.de/kmp/technology/K-mount/Kaf.html> at Boz's K mount technical page), on it's female mount. Without that pin there can be no communication between the lens and camera, so the camera has no ability to treat the lens as anything other than an "A" lens.
