And more: with non A lenses, P-TTL isn't available !
Hrm... that's a rather significant limitation, no? How does P-TTL differ from TTL? I'm assuming that in P-TTL the camera wants to know how far away the subject focus is so it doesn't like not knowing.
Anyone tried to reverse-engineer the serial protocol on the data pin for the KAF/KAF2 lenses? I looked for awhile, but no luck.
